Your swimming fun starts with clear, clean water. You will have to measure pH and Chlorine values on a regular basis to establish this, so you can add chemicals if necessary to keep these values at the right levels. After opening the packaging, the digital test set is ready for use. Hold the test trip for some seconds in the water and place it in the strip window of the digital test set. Within seconds you can read the values (pH, chlorine and alkalinity) or your pool water. The digital test set
comes with 25 test strips.
