Water quality testing equipment
For water quality testing, we supply the Horiba, XS Instruments range, Eutech Instruments, Sensafe eXact, Extech, Milawauke and Lamotte ranges for water quality testing.
We select equipment based on your application, be it industrial process lines, hand held meters or bench top models. For example, the Sensafe eXact range of photometers can measure parameters such as nitrate, nitrates and phosphates.
Many water quality parameters can be tested
Ecotao offers solutions for all common water quality parameters: pH, salinity, temperature, conductivity, salinity, total dissolved solids, various ions (colorimetry and probes), turbidity and more.
We supply a range of options for testing water ranging from test strips, to pocket testers, single parameter meters, multi-parameter meters and bench-top meters.

Water quality brands we supply
Ecotao carries ten water quality testing brands, each suited to a different way of working: pocket testers for spot checks in the field, photometers and reagent kits for colorimetric parameters, laboratory benchtop instruments for controlled measurement, and online analysers for continuous process monitoring. The summary below shows what each brand is best suited to, so you can start from the application rather than the catalogue.
Horiba
Best for compact field measurement on very small samples
Japanese precision instruments spanning the LAQUAtwin pocket range, LAQUA 200 and 300 Series handhelds, the U-50 multi-parameter water quality checker and LAQUA 1500 and 2000 benchtop meters. The LAQUAtwin flat sensor measures a few drops, which makes it useful where sample volume is limited.
XS Instruments
Best for a full tester-to-benchtop range from one supplier
Italian-built meters covering waterproof pocket testers (Tester series 1 and 5), portable pH, conductivity and dissolved oxygen meters (pH 7/70, PC 7/70, OXY 7/70, COND 7/70) and bench models including the DHS self-recognising electrode range.
Eutech Instruments
Best for routine laboratory pH, conductivity and TDS
Established laboratory and field instrumentation for pH, ORP, conductivity, resistivity, salinity and total dissolved solids, in pocket tester, portable and benchtop formats.
Sensafe eXact
Best for fast colorimetric testing without reagent handling
Photometers and strip-based systems from Industrial Test Systems, including the eXact iDip Bluetooth photometer, the eXact Micro 20, the Micro 7+ and the eXact Eco-Check kit. Covers chlorine, nitrate, nitrite, phosphate, alkalinity, hardness and a long list of further parameters.
Extech
Best for general purpose meters across many parameters
A broad instrument range covering pH and ORP, conductivity, salinity and TDS, dissolved oxygen, chlorine, fluoride and turbidity, plus multi-parameter kits. Replacement probes, consumables and accessories are stocked alongside the meters.
Milwaukee
Best for straightforward everyday testing on a working budget
Practical pH, EC, TDS and ORP testers and portable meters used widely in agriculture, hydroponics, pools, aquaculture and food and beverage production.
Hanna Instruments
Best for turbidity measurement and direct soil pH
Turbidity meters for potable water, process water and environmental monitoring, along with the direct soil pH measurement kit used in agricultural testing.
Lamotte
Best for reagent test kits matched to a specific water type
Colorimetric test kits, pocket testers and method-specific outfits grouped by application: aquaculture, aquarium and pond, potable drinking water, waste water and sewage, environmental management, soil testing and microbiological testing.
Specialised Equipment
Best for parameters the standard meters do not cover
Portable nitrate, ammonium, ammonia and turbidity meters, plus online multi-parameter sensors able to read up to eight parameters at once, including COD, suspended solids, chlorophyll, blue-green algae and oil in water.
Chemins Instruments
Best for continuous online monitoring and process control
Online analysers, monitoring systems, controllers and portable instruments for installed water quality applications such as treatment plants, process lines and effluent monitoring.
