Moisture Meters23 models

A moisture meter estimates how much water a material holds, shown as percentage moisture content (%MC) or as a relative reading. Pin-type meters measure electrical resistance between two pins pushed into the material. Pinless (search or inductive) meters read through the surface using a capacitive or inductive field, so they leave no holes. Combination meters do both.

Handheld grain moisture meter with digital display, one of the moisture meter types on this page

How to choose

  • Pin type when you need a reading at a known depth in timber, and small pin holes are acceptable.
  • Search / inductive (pinless) for finished surfaces, flooring, plaster and quick scanning of large areas for damp patches.
  • Pin & search (MC-7825PS) if one instrument must cover both jobs.
  • Material-specific meters for paper (MD916) and grain (MD7822), which are calibrated for those materials rather than timber.

Typical applications: Timber drying and furniture manufacture, flooring installation checks, damp surveys on walls and screeds before painting or tiling, paper and packaging QC, and grain storage.

Humidity & Temperature Meters9 models

A humidity and temperature meter (thermo-hygrometer) measures relative humidity (%RH) and air temperature together. Relative humidity is the amount of water vapour in the air as a percentage of the maximum the air can hold at that temperature, so the two readings always belong together.

How to choose

  • Handheld meters (HT and AR series) for spot readings on site, in HVAC ducts and in storerooms.
  • Thermo-hygrometers (GR series) for continuous display in a room, warehouse or laboratory.
  • Need a record over days or weeks? Use a datalogger instead.

Typical applications: Warehouse and cold-chain storage, museums and archives, HVAC commissioning, paint and coating application (which needs controlled humidity), and laboratories.

Dew Point Meters4 models

A dew point meter calculates the temperature at which water vapour in the air will condense, from measured air temperature and relative humidity. If a surface is colder than the dew point, condensation forms on it.

How to choose

  • Use a dew point meter when you need to know whether a surface will stay dry: before painting steel, in cold rooms, and when tracing condensation in buildings.
  • Coating specifications commonly require the steel surface to be at least 3 °C above dew point before application, so a dew point reading is a standard pre-painting check.

Typical applications: Protective coating and corrosion work, HVAC and refrigeration, building condensation surveys.

Dataloggers3 models

A datalogger records readings automatically at set intervals and stores them for download, so you get a full record over hours, days or weeks instead of a single spot reading.

How to choose

  • Temperature & humidity loggers (HT-150, HT-155) for storerooms, transport and archives.
  • Dual temperature logger (HT-620) when two temperature points must be recorded at once, for example inside and outside a cold room.

Typical applications: Cold-chain and pharmaceutical storage records, food safety, warehouse audits, and building climate studies.

Anemometers13 models

An anemometer measures air velocity. Vane anemometers use a small rotating impeller. Some models also calculate airflow volume (velocity × duct area) and measure air temperature, which makes them the standard tool for HVAC balancing and ventilation checks.

How to choose

  • Velocity only for wind and outlet checks; choose a model with volume (CFM/CMM) calculation for duct balancing.
  • Models with a separate vane on a cable are easier to use in ducts and at ceiling grilles.
  • Ask Ecotao for each model's velocity range and whether it measures temperature.

Typical applications: HVAC commissioning, fume-cupboard and extraction checks, mine and tunnel ventilation, outdoor work-at-height wind checks, and agricultural spraying.

Lux Meters & UV Light Meters10 models

A lux meter measures illuminance: the amount of visible light falling on a surface, in lux (lumens per square metre). A UV light meter measures ultraviolet irradiance, which a lux meter cannot see.

How to choose

  • Use a lux meter to check work areas against required lighting levels and to verify lighting after installation or maintenance.
  • Use the UV340B for UV curing lamps, UV disinfection equipment and UV exposure checks.

Typical applications: Workplace lighting surveys, offices, warehouses, schools, factories, sports facilities, photography and greenhouse lighting.

Sound Level Meters & Calibrators14 models

A sound level meter measures sound pressure level in decibels (dB), usually with A-weighting (dBA) to match how the human ear responds. A sound level calibrator produces a known reference tone so you can check the meter's accuracy before and after each measurement.

How to choose

  • For workplace noise assessments, use a meter with A-weighting and slow/fast time response, and check it with a calibrator before every survey.
  • The SL-5868P is the multifunction model in this range. Ask Ecotao about its functions.
  • Formal noise-exposure surveys are carried out by approved inspection authorities. A handheld meter is the right tool for in-house checks, identifying noisy machines and checking that controls work.

Typical applications: Factory and mine noise checks, identifying hearing-protection zones, environmental and neighbourhood noise, events and venues, and machinery noise comparisons.

Thickness, coatings, flaws & surface finish

Ultrasonic Thickness Gauges15 models

An ultrasonic thickness gauge measures the wall thickness of a material from one side only. A probe sends a pulse of sound through the material and times the echo from the far wall. Thickness = sound velocity × time ÷ 2. That makes it the standard tool for checking corrosion loss in pipes, tanks and hulls without cutting or drilling.

How to choose

  • Set or select the correct sound velocity for the material (steel, aluminium, plastic, glass). A wrong velocity gives a wrong thickness.
  • Always use couplant gel between probe and surface. Air blocks ultrasound.
  • Ask Ecotao about through-paint (echo-echo) capability if you need to measure coated steel without removing the coating.

Typical applications: Pressure vessel and pipeline inspection, storage tanks, ship hulls, boiler tubes, structural steel corrosion surveys, and wall-thickness checks on castings and plastics.

Coating Thickness Gauges21 models

A coating thickness gauge measures the dry film thickness (DFT) of paint, powder coat, galvanising, plating or anodising on a metal base, without damaging the coating. F (ferrous) gauges use magnetic induction on steel and iron. N or NF (non-ferrous) gauges use eddy currents on aluminium, copper and other non-magnetic metals. FN gauges do both.

How to choose

  • Only steel substrates? An F model is enough.
  • Only aluminium or other non-ferrous metals? Choose N / NF.
  • Mixed work (fabricators, paint inspectors, powder coaters)? Choose FN so one gauge covers both.
  • Calibrate (zero and foil) on an uncoated sample of the same metal before measuring.

Typical applications: Powder coating and spray painting QC, hot-dip galvanising checks, corrosion-protection inspection on structural steel, automotive paint inspection, and anodising lines.

Ultrasonic Flaw Detectors8 models

An ultrasonic flaw detector sends high-frequency sound into a part and displays the returning echoes (an A-scan). Cracks, porosity, lack of fusion and laminations reflect sound and show up as echoes before the back wall, so hidden defects can be found and sized without cutting the part.

Digital ultrasonic flaw detector with A-scan display for weld and casting inspection

How to choose

  • Ultrasonic flaw detection is operator-dependent. Results are only as good as the technician's training, probe selection and calibration blocks.
  • Choose a model supplied with standard accessories (YUT2600, YUT2620, YUT2800, YUT2820) if you are starting without probes and cables.
  • Ask Ecotao about probe options (straight beam, angle beam) for your application.

Typical applications: Weld inspection on structural steel, pipelines and pressure vessels, castings and forgings, rail, and in-service crack detection in mining and heavy industry.

Surface Roughness Testers9 models

A surface roughness tester (profilometer) drags a fine diamond stylus across a surface and calculates roughness parameters such as Ra (arithmetic mean roughness) and Rz (mean peak-to-valley height). The laser model measures without contact.

How to choose

  • Stylus testers suit most machined metal parts. Check the part is clean and the stylus can reach the area.
  • Choose the TRL400 laser roughness tester where contact is not allowed or the surface is soft.
  • Ask Ecotao which parameters (Ra, Rz, Rq, Rt and others) each model reports.

Typical applications: Machining and grinding QC, bearing and seal surfaces, hydraulic components, surface preparation checks before coating, and incoming-goods inspection.

Gloss Meters7 models

A gloss meter shines light onto a surface at a fixed angle and measures how much is reflected in the mirror direction, in gloss units (GU). The angle matters: 60° is the general-purpose angle, 20° separates high-gloss finishes, and 85° separates low-gloss and matt finishes.

Portable gloss meter for measuring surface gloss in gloss units on paint and coatings

How to choose

  • One finish type, mid-gloss? A single-angle 60° meter is enough.
  • High-gloss work such as automotive paint and lacquer? Add 20° (MG26-F2 or MG268-F2).
  • Matt and satin finishes? Add 85° (MG68-F2 or MG268-F2).
  • Mixed work across all finishes: the tri-angle MG268-F2.

Typical applications: Paint and coatings manufacture, automotive refinishing, furniture and cabinetry, stone and tile polishing, plastics, printing and packaging.

Hardness testers

Shore Durometers & Fruit Sclerometers15 models

A Shore durometer measures the hardness of rubber, elastomers and plastics by how far a spring-loaded indenter sinks into the surface, on a 0 to 100 scale. Shore A is for soft rubber and elastomers, Shore D for hard rubber and rigid plastics, and Shore C for medium-soft materials such as foams. A fruit sclerometer (penetrometer) measures fruit firmness to judge ripeness.

How to choose

  • Pick the scale for the material: A for tyres, seals, belts and soft rubber; D for hard plastics and hard rubber; C for microcellular materials and foams.
  • Dual-needle durometers hold the maximum reading so you can read it after lifting the gauge.
  • Use a durometer test stand (LAC-J, LD-J) for repeatable readings: it applies a consistent force and keeps the gauge square to the sample.

Typical applications: Rubber and plastics manufacturing, conveyor belts, seals and gaskets, tyre and roller checks, and fruit harvest timing and packhouse QC.

Leeb (Portable Rebound) Hardness Testers11 models

A Leeb hardness tester fires a small impact body at the surface and compares its rebound speed with its impact speed. Harder metals give a higher rebound. The Leeb value (HL) is converted on the instrument to Brinell, Rockwell, Vickers or Shore scales. Because it is handheld, it can test large or installed parts that will not fit in a bench tester.

How to choose

  • Best for large, heavy or installed metal parts: shafts, rolls, castings, pipes, structural steel.
  • The part needs enough mass and thickness, and a smooth, clean test spot. Thin or light parts give unreliable readings.
  • Converted values are estimates. Where a specification requires a true Brinell, Rockwell or Vickers number, use a bench tester.

Typical applications: Incoming steel checks, heat-treatment verification, mining and earthmoving wear parts, rolls and shafts in service, and weld and heat-affected-zone surveys.

Brinell Hardness Testers12 models

A Brinell hardness tester presses a hard ball into the metal under a fixed load, then the diameter of the round indentation is measured. The large indentation averages out coarse grain structure, which makes Brinell the preferred method for castings, forgings and soft-to-medium-hard metals.

How to choose

  • Standard and digital-display models for workshop and lab use; the digital models show the result directly.
  • Gate-type (HBM-3000B) for large or long workpieces that will not fit under a standard frame.
  • Low-load (HBS-62.5) for soft metals, thin sections and small parts.
  • Automatic (HBZ-3000A) for higher-volume testing.

Typical applications: Foundries, forging shops, steel and aluminium suppliers, heat-treatment verification, and incoming-goods inspection.

Rockwell Hardness Testers12 models

A Rockwell hardness tester applies a minor load, then a major load, through a diamond cone or a steel ball, and measures the permanent increase in indentation depth. The result reads directly, with no optical measurement, so Rockwell is the fastest bench method and the usual choice for production QC of heat-treated steel.

How to choose

  • Standard Rockwell (HRC, HRB and related scales) for most steels and non-ferrous metals.
  • Superficial Rockwell (HSRS-45, HSRD-45) for thin material, case-hardened layers and small parts.
  • Plastic Rockwell (XHRD-150) for plastics.
  • Motor-driven and automatic full-scale models reduce operator influence and speed up testing.

Typical applications: Heat-treatment shops, tool and die makers, bearing and fastener manufacturing, and production QC.

Vickers & Microhardness Testers16 models

A Vickers hardness tester presses a square-based diamond pyramid into the material and measures the two diagonals of the indentation under a microscope. One indenter covers everything from soft metals to very hard steels and ceramics. At low loads (microhardness) it can test thin coatings, case depth and individual phases in a metallographic sample.

How to choose

  • Microhardness testers (HV-1000 and HVS-1000 series) for thin layers, small parts, case-depth profiles and metallography.
  • Low-load Vickers (HV-5, HV-10B, HVS-5) for thin sections and small components.
  • Standard Vickers (HV-50A, HVS-50, 200HV-5) for general testing.
  • Add the CCD image processing system or the SP-5 video measuring apparatus to measure indentations on screen instead of through the eyepiece.

Typical applications: Metallurgical laboratories, heat-treatment and surface-hardening QC, coatings, welding procedure qualification, and research.

Hardness test methods compared: Shore vs Leeb vs Brinell vs Rockwell vs Vickers

Each method measures resistance to indentation in a different way, so results are not directly interchangeable. Conversion tables exist between metal scales, but they are approximate. Where a drawing or specification names a scale (for example HRC or HB), test with that method.

Force, tension, torque & test stands

Force Gauges (Push-Pull)37 models

A force gauge measures push (compression) or pull (tension) force, in newtons (N). Analog (NK series) gauges use a spring and dial. Digital (HF series) gauges use a load cell and show peak and live readings. Mounted on a test stand, either becomes a simple, repeatable tensile or compression tester.

How to choose

  • Choose a capacity a little above your highest expected force. Resolution is better on a lower-capacity gauge, so do not oversize by much.
  • Analog NK gauges (10 to 500 N) are simple and need no batteries. Digital HF gauges (2 N to 3000 kN) record peak values and suit QC work.
  • From 100 kN upward the HF range is listed in push-only and pull-push versions. Confirm which one you need.

Typical applications: Spring, switch and button testing, connector and crimp pull-off, packaging and closure tests, furniture and textiles, and production line QC.

Tension Meters (ATN & ATG) & Belt Tension Tester33 models

A tension meter measures the tension in a running or stationary thread, wire, yarn, film or fibre. The line runs over guide rollers on the meter, and the deflection force is shown on a dial. ATN models are graduated in newtons (0.05 to 5 N); ATG models in grams (5 to 500 g) for very fine threads. A belt tension tester checks drive-belt tension.

How to choose

  • Pick a capacity just above your normal running tension for the best resolution.
  • Dual needle versions hold the peak reading; single needle versions show live tension only.
  • Use the BTT-2880 for V-belts and timing belts on drives and conveyors.

Typical applications: Textile and yarn processing, wire drawing and coil winding, cable manufacture, film and tape converting, and belt-drive maintenance.

Torque Gauges & Cap Torque Testers42 models

A digital torque gauge measures twisting force (torque) applied to a fastener, cap, knob or shaft. ANL torque gauges test general components. ANL-P cap torque testers clamp a bottle or jar and measure the torque needed to open or close the cap, from 1 to 20 N·m. Models with a built-in printer give a paper record of each test.

How to choose

  • Cap torque testers (ANL-WP and ANL-P) for bottles, jars and closures. Choose a capacity above your highest removal torque.
  • Printer versions (models ending in P) if you need a paper record for QC files without a computer.
  • The ANL series is listed by capacity code (ANL-1 to ANL-5000). Ask Ecotao to confirm the torque range and unit for the model you need.

Typical applications: Beverage, pharmaceutical, cosmetic and food packaging lines, switch and knob testing, and small fastener checks.

Test Stands & Spring Testers47 models

A test stand holds a force gauge and drives it into or away from the sample at a controlled rate, so readings are repeatable. Manual stands are wheel- or lever-operated; electric stands run at a set speed. A ruler (standard or digital) on the stand records displacement, so you can see force against distance. Digital spring testers measure spring force at a set compression or extension.

How to choose

  • Up to 500 N: manual stands (ALX, AST, ASC, ASL) or the electric AEL.
  • Higher loads: AEV electric vertical stands from 5000 N to 30 000 N.
  • Need displacement? Choose a version with a digital ruler (models ending in -S).
  • Special tests: ABL-90 for 90° peel tests, AAJ for keyboard and keystroke testing, AMH and AEH for horizontal pulling.
  • Springs: ATH digital spring testers, 10 to 5000 N, with or without a printer.

Typical applications: Production QC, spring manufacture, adhesive and label peel tests, switch and keypad testing, and incoming-goods checks.

Rotation, vibration & temperature

Tachometers & Stroboscopes25 models

A tachometer measures rotational speed in revolutions per minute (RPM). Photo (laser) tachometers read a reflective tape mark from a distance, so you do not touch the moving part. Contact tachometers press a rubber tip or wheel against the shaft, and can also measure surface (linear) speed. A stroboscope flashes at a set rate so a moving part appears frozen, for checking speed and inspecting it while it runs.

How to choose

  • Photo/laser for safe, non-contact readings on fans, motors and pulleys.
  • Contact for surface speed of belts, conveyors, rollers and paper or film lines.
  • Photo/contact combination models do both.
  • Engine tachometers (GED-2600, GED-2600P, SM8237) read engine RPM.
  • Stroboscopes to inspect running machinery, for example blades, gears, printing and textile lines. Pick a flash range (FPM) that covers your machine speed.

Typical applications: Motor and fan maintenance, conveyor speed, printing and packaging lines, engines and generators, and machine commissioning.

Vibration Meters6 models

A vibration meter measures machine vibration with an accelerometer, normally as acceleration, velocity and displacement. Rising vibration is one of the earliest signs of imbalance, misalignment, looseness or bearing wear, so regular readings let you plan repairs before a breakdown.

How to choose

  • Velocity (mm/s) is the usual parameter for comparing general machinery condition against severity guidelines.
  • A detached probe (AR63B) reaches tight spots and gives steadier readings than holding the whole meter against the machine.
  • The VM-6360 comes with a cable and software (RS232C) for transferring readings to a computer.

Typical applications: Predictive maintenance of pumps, fans, motors, compressors and gearboxes in mining, water treatment, manufacturing and HVAC plant.

Infrared Thermometers21 models

An infrared thermometer measures surface temperature without contact by reading the infrared energy a surface emits. It is fast and safe for moving, live, hot or hard-to-reach surfaces. Two things decide accuracy: the distance-to-spot ratio (how big the measured area is at a given distance) and the surface's emissivity (shiny metals read low unless emissivity is adjusted or the surface is taped or painted).

How to choose

  • Choose a range that covers your highest temperature with margin: up to 300–550 °C for HVAC, electrical and food; up to 850–1500 °C for kilns, furnaces and molten metal; 200 to 2200 °C models for very high-temperature process work.
  • For shiny metal, choose a model with adjustable emissivity, or apply a high-emissivity tape or paint to the spot.
  • Infrared thermometers read the surface only, not the core. Use a probe thermometer for internal food temperatures.
  • The AF110 is a forehead thermometer (30 to 45 °C), designed for body temperature, not industrial surfaces.

Typical applications: Electrical panel and motor hotspots, HVAC, food service and cold chain, kilns, furnaces, foundries and asphalt laying.

Insulation Resistance Testers7 models

An insulation resistance tester applies a high DC test voltage to a cable, motor winding or installation and measures the resistance of its insulation, usually in megohms (MΩ) or gigohms (GΩ). Low insulation resistance points to moisture, contamination or damaged insulation before it causes a fault.

AR3126 high-voltage insulation resistance tester for cables, motors and switchgear

How to choose

  • Match the test voltage to the equipment's rated voltage. Low-voltage installations use lower test voltages; motors, cables and switchgear on medium voltage need a higher-voltage tester such as the AR3126.
  • Make sure the circuit is isolated and safe before testing, and discharge it afterwards.
  • Ask Ecotao for the test voltages and resistance range of each model.

Typical applications: Electrical installation testing and Certificates of Compliance, motor and generator maintenance, cable commissioning, transformer and switchgear maintenance, and mining electrical work.

Range Finders & Distance Meters5 models

A distance meter measures the distance from the instrument to a target. Laser distance meters time a laser beam and are the most precise. Ultrasonic range finders use sound and are best for quick room measurements to a flat wall.

How to choose

  • Laser (AR861, AR881) for precise measuring, longer distances and small targets.
  • Ultrasonic (AR831, AR841, AR851) for quick, rough room measurements.

Typical applications: Estimating, quantity surveying, real estate, interior fit-out and flooring, and site measurement.

Gas Detectors7 models

A portable gas detector senses a specific gas and alarms when its concentration passes a set level. Each detector is built for particular gases: carbon monoxide (CO), oxygen (O2) level, combustible gases, refrigerants or sulphur hexafluoride (SF6).

How to choose

  • Choose by the gas you need to detect. A CO meter will not detect combustible gas, and the reverse is also true.
  • Oxygen detectors are for confined-space entry, where oxygen can be too low.
  • Leak detectors (refrigerant, SF6) find the source of a leak. Personal alarms (SPD series) warn the wearer.
  • Gas sensors age, so plan regular bump tests and calibration.

Typical applications: Confined-space entry, boiler rooms and kitchens (CO), fuel and gas installations, HVAC and refrigeration leak finding, and SF6 switchgear maintenance.

Precision meters and South African workplace regulations

On 6 March 2025 the Department of Employment and Labour promulgated the Noise Exposure Regulations, 2024 and the Physical Agents Regulations, 2024 under the Occupational Health and Safety Act, 1993. They replaced the Noise-Induced Hearing Loss Regulations, 2003 and the Environmental Regulations for Workplaces, 1987, which were repealed 18 months after promulgation, on 6 September 2026.

The Physical Agents Regulations cover hazards such as illumination, vibration, heat stress, cold stress and non-ionising radiation. Employers need to identify and control exposure to these agents, and measurement is how you show where a problem exists and whether controls work. Instruments on this page that support that work:

Formal exposure assessments may have to be done by an approved inspection authority or another person the regulations specify. Check the regulations for your site. Handheld meters are the right tools for in-house checks, follow-up after changes, and confirming that controls are working.

Other South African uses: insulation resistance testing is part of electrical installation testing before a Certificate of Compliance is issued; coating thickness and dew point checks are part of corrosion-protection work on coastal and mining infrastructure; and moisture meters are used across timber processing and building damp surveys.

Precision meters: frequently asked questions

What is a precision meter?

A precision meter is a measuring instrument that gives a numerical reading of a physical property, such as moisture content, hardness, thickness, force, sound level, illuminance, rotational speed or temperature, so the result can be recorded and compared with a specification. Ecotao supplies 437 precision meter models in 29 instrument types, from moisture meters and lux meters to hardness testers, force gauges and ultrasonic flaw detectors.

What is the difference between a pin and a pinless moisture meter?

A pin moisture meter measures electrical resistance between two pins pushed into the material, giving a reading at the pin depth but leaving small holes. A pinless (search or inductive) meter reads through the surface with an electromagnetic field and leaves no marks, which suits finished timber, floors and walls. Combination meters such as the MC-7825PS do both.

Which hardness tester do I need: Shore, Leeb, Brinell, Rockwell or Vickers?

Use a Shore durometer for rubber and plastics. Use a Leeb tester for large or installed metal parts that cannot be brought to a bench. Use Brinell for castings, forgings and coarse-grained metals, Rockwell for fast production checks on heat-treated steel, and Vickers or microhardness for thin layers, coatings, small parts and metallography. If a specification names a scale, test with that method.

What is the difference between F, N and FN coating thickness gauges?

F (ferrous) gauges use magnetic induction to measure coatings on steel and iron. N or NF (non-ferrous) gauges use eddy currents to measure non-conductive coatings on aluminium, copper and other non-magnetic metals. FN gauges combine both, so one instrument covers steel and aluminium.

How does an ultrasonic thickness gauge measure thickness from one side?

The probe sends a pulse of ultrasound into the material and times the echo from the far wall. The gauge calculates thickness from the sound velocity of the material and half the round-trip time. This is why the correct material velocity must be set and couplant gel must be used between probe and surface.

Which gloss meter angle should I use: 20°, 60° or 85°?

60° is the general-purpose angle for most finishes. 20° gives better separation on high-gloss finishes such as automotive paint and lacquer. 85° gives better separation on low-gloss and matt finishes. A tri-angle meter such as the MG268-F2 covers all three.

How do I choose the right capacity for a force gauge?

Choose a capacity slightly above the highest force you expect to measure. A gauge that is much larger than needed has coarser resolution at low forces. Ecotao lists NK analog gauges from 10 to 500 N and HF digital gauges from 2 N to 3000 kN, with push-only and pull-push versions from 100 kN.

Can an infrared thermometer measure shiny metal accurately?

Shiny metals have low emissivity, so an infrared thermometer set for normal surfaces will read them too low. Adjust the emissivity setting if the model has one, or put high-emissivity tape or paint on the measuring spot. Infrared thermometers measure surface temperature only, not the internal temperature.

Which South African regulations call for noise, lighting and vibration measurement?

The Noise Exposure Regulations, 2024 and the Physical Agents Regulations, 2024, made under the Occupational Health and Safety Act and promulgated on 6 March 2025, replaced the Noise-Induced Hearing Loss Regulations, 2003 and the Environmental Regulations for Workplaces, 1987 from 6 September 2026. The Physical Agents Regulations cover illumination, vibration, heat and cold stress and non-ionising radiation. Sound level meters, lux meters, vibration meters and humidity and temperature meters support in-house checks under these regulations.
