DPD 4 tablets are designed for measuring the concentration of active oxygen (peroxo compounds) in pools with chlorine-free OXY system disinfection.
Simply place the tablet in the tester chamber, add a water sample, and compare the resulting colour with the colour scale – the result is available within a few seconds.
The pack contains 10 tablets, which are sufficient for regular daily or weekly water quality checks throughout the season.
Regular testing ensures that the disinfectant level remains within the recommended range and protects the health of bathers.
