The Pooltester is an easy to use tool for measuring free available chlorine, total chlorine and pH (acidity) of water samples. It is a visual, colour comparator test and uses reagent tablets, which colour the sample water water according to the presence of chlorine or the pH. LetzTest especially recommends this kit to test for residual chlorine in areas of limited infrastructure.

Note:  A small number of reagent tablets are included with the unit but larger quantities should be requested separately.
Phenol Red - for pH
DPD1 - for free/residual chlorine
DPD3 - for total chlorine (used with DPD1)
