Which Digital Water Tester?

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? Here are our options:

eXact iDip 570 Photometer Marine Starter Kit (salt water)1) The eXact iDip & iDip 570
Can test more than 30 different elements. 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 user can add new tests via the app from a selection of over 30 tests (see list below) and therefore personalise the photometer to their specific requirement. The app also includes clear instructions (including videos) on how to carry out the tests and is therefore very easy to use.

eXact Micro 20 Photometer Bluetooth Digital Water Tester2) 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.

eXact EZ Photometer Pool Advanced Kit3) 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.

To carry out a test with a digital water tester, you need:

  • To purchase the Digital Water Tester of your choice, as well as reagent/test strips for that test, available on our website
  • For eXact iDip® & eXact iDip® 570 only: download & install each test from the app-store (approx. from £4.95 each) – this is a one-off cost. Once a test has been downloaded onto your smart device from the app-store it can be used indefinitely. Both devices come with 4 tests pre-installed: pH, DPD-1 Free Chlorine, DPD-3 Combined Chlorine and Total Alkalinity.

All photometers are also available in ready made kits for different uses, including:

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