Industrial Test Systems (ITS) – water quality

ITS (Sensafe range) is a leading American manufacturer and innovator of water quality testing and has a unique photometer range for water quality testing.

Their latest innovation, the eXact iDip® Smart Photometer System®, tests over 45 important water parameters paired with a smartphone/tablet using the the eXact iDip® free app.

Current models

Different photometers have different capabilities and are priced accordingly.

The BlueTooth iDip models are factory calibrated through the phone app, so never need calibration.

eXact photometers

The digital, portable, hand-held water quality analysers allow a wide range of parameters measuring including free and total chlorine, pH, bromine, total alkalinity, calcium as CaCO3, copper and transmission and many other water parameters as outlined below. Convenient, fast, simple, all you have to do is to fill sample, dip strip and measure with the press of a button. There is no need to change sensors for different parameter measurement.

No visual colour matching required means the eXact® Eco-Check and other meters take the guesswork out of water testing.


eXact series meter is IP67 water proof and designed with sample holder inside so user can collect sample directly using the meter which saves a lot of consumables and chemicals.  With battery powered it is applicable on field use such as pool, spa, drinking water quality testing.


Suitable for field testing

eXact series can test as many as 36 parameters in one system with relating strips. 

  • Micro 7+ can read free and total chlorine, pH, alkalinity, hardness, iron, and copper etc. 
  • Micro 8 can read ammonia, cyanide, phosphate, and sulphate etc. 
  • LeadQuick can measure heavy metals in water such as lead, mercury, and cadmium.  The application field is very wide including pools, spa, drinking water, aquarium and food industry.
