Digital Water Testers (also called photometers) are a great way to measure various elements in water fast and accurately. Our range is reliable, does not need calibrating and has a manufacturers warranty of 2 years.
Looking for the right Digital Water Tester? Please see the table below to compare the different types and the parameters they can test.
Here are our options with a brief summary for each:
1) The eXact iDip & iDip 570
Can test more than 30 different elements – the user can customise the iDip from a selection of over 30 tests (see list below). The iDip is operated through a specifically developed app on your smart phone or tablet (iPhone®, iPad®, and iPod Touch®, Android®). Test results can be downloaded from the app in real time with parameter information, data storage as well as date/time/location tracking of the tests. The iDip comes with 4 tests pre-installed (pH, Free Chlorine, Combined Chlorine and Total Alkalinity). The app also includes clear instructions (including videos) on how to carry out the tests and is therefore very easy to use.
2) Micro 20 Bluetooth range
Can test more than 30 different elements. All tests are pre-installed and the Micro 20 can be used on its own or be linked to a smart device via Bluetooth. Test results can be downloaded onto smart phone or tablet (iPhone®, iPad®, and iPod Touch®, Android®) in real time with parameter information, data storage as well as date/time/location tracking of the tests.
3) eXact EZ Photometer Digital Water Tester
Each photometer in the range tests a set range of elements accurately and reliably. The test results are displayed on the photometer.
4) PoolLab 1.0 Digital Photometer for pool, spa & hot tub (including saltwater and salt electrolysis pool)
This triple wavelength photometer, developed in Germany, tests reliably and accurately for up to 13 parameters: Active Oxygen (MPS), Alkalinity, Bromine, Total/Combined/Free Chlorine, Cyanuric Acid, Chlorine Dioxide, Hydrogen Peroxide (low range + high range), Calcium hardness, Total Hardness, Ozone, pH, Urea and PHMB (Polyhexamethylbiguanide).

New tests are always added to the photometers, so please check back from time to time or contact us for more details.
