Which Digital Water Tester?
Digital Water Testers (also called Photometers) are a great way to measure various elements in water fast and accurately.
Looking for the right Digital Water Tester? Here are our options:
1) eXact EZ Photometer Digital Water Tester - each tests a set range of elements. The test results are displayed on the photometer. Currently available are:
- eXact EZ Photometer Pool Starter Kit to test Total Alkalinity, Calcium Hardness, free/total & combined Chlorine, Chloride, Copper, Cyanuric Acid, pH and Phosphate.
2) The eXact iDip & Micro 20 Bluetooth range - can test more than 30 different elements. Test results can be downloaded onto smart phone or pad (iPhone®, iPad®, and iPod Touch®, Android®) in real time with parameter information, data storage and GPS tracking (to record the location of the tests) .
The eXact iDip®, eXact iDip® 570 and eXact® Micro 20 are able to test a wide range of parameters. We have compiled a complete list of elements in the table below to help you choose the product suitable for your test needs.
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 (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:
- eXact® iDip® - Photometer Smart Brew® Digital Water Test Kit,
- eXact® iDip® 570 - Photometer Aquarium Starter Kit (fresh water),
- eXact iDip® 570 - Photometer Marine Starter Kit (salt water),
- eXact® LeadQuick - Photometer for Lead in Water
- eXact® iDip® Photometer Smart Pool Digital Water Tester
- eXact Micro 20 - Photometer for Fluoride
- eXact Micro 20 - Photometer for Manganese
New tests are always added to the photometers, so please check back from time to time or contact us for more details.
