pH/Chlorine Testing Kit
Tester and tablets that easily measure the pH value and chlorine level in pools or hot tubs. It is necessary to regularly check the water to ensure the pH value and chlorine level are within the optimal range: the pH value should be between 7.0 and 7.4, and the chlorine level should be between 0.6 and 1.0 mg/l in a pool or 1 - 1.5 mg/l in a hot tub. The tester has two chambers into which water is poured. One tablet (Phenol Red) is placed in the left water-filled chamber to measure the pH value, and another tablet (DPD1) is placed in the right-hand chamber to measure chlorine. The tablets dissolve and colour the water. Compare the colour of the water to the colour scale next to the chamber to determine the pH value and chlorine level.
