Ocean pH/Cl tester

Tester is used to test free (active) chlorine and the pH of pool water. To keep your pool water crystal clear, its use is absolutely essential. First measure the pool water values and if they are not within the normal range (pH 6.9-7.2; Cl 0.3-0.7), adjust the pool water using pool chemicals. First adjust the pH value (pH+ or pH-) and then adjust the chlorine level (only increase - if the chlorine value is too high, do not decrease it, it will drop on its own in a few days). Chlorine is applied only after pH regulation because the effectiveness of chlorine outside the recommended pH value rapidly declines

The DPD tester works on the principle of visual comparison with a color chart next to the sampling chambers - after adding tablets (chlorine/pH) the water colors, according to the results it is necessary to adjust the chlorine/pH in the pool
