Do you have a digital tester that works using tablets? Do you want to measure the free chlorine value of your water? You can do this using DPD no. 1 tablets. These tablets enable you to test 100x the free chlorine value. Each tablet is suitable for one measurement.
The tablets are suitable for digital testers, such as the Lovibond Scuba II tester.
The free chlorine value indicates how much working, disinfecting chlorine the water contains.
Bonded chlorine value indicates how much non-working, non-disinfecting chlorine the water contains.
Total chlorine value indicates how much free and bound chlorine there is together in the water.
