DPD Tablet Test 3 CL - 10 pcs (Total Chlorine)

Product detailed description

The tester is used to test free (active) chlorine and pool water pH. In order to keep your pool water crystal clear, its use is absolutely necessary. First measure the pool water values ​​and if they are not standard (pH 6.9-7.4; cl 0.3-0.7), adjust the pool water using pool chemistry. First, adjust the pH (PH+ or PH-) value and then adjust the chlorine value (only increase-if the chlorine value is too high, do not reduce it, it will drop in a few days). Chlorine is applied only after the pH regulation because the efficiency of chlorine outside the recommended pH values ​​decreases rapidly
