Tester DPD "D" - OXY/PH - method using tablets, lovibond, color: blue

The tester is used to test the oxygen and the pH of the pool water. 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; & nbsp; 2 3.0-8.0 mg/l), adjust the pool water using pool chemistry. First, adjust the pH (PH+ or PH-) value and subsequently adjust the Oxygen (only increase-if the chlorine value is too high, do not reduce it, falls in a few days). & Nbsp; oxygen is only applied to pH regulation because the efficacy of Oxygen outside the recommended ph values ​​decreases rapidly Tester DPD works on the principle of visual comparison with a colorful sampler next to the supply chambers - after adding tablets (oxy/pH) the water is colored, according to the results it is necessary to adjust the value of the oxy/ph in the pool
