For the water treatment of swimming pools, it is essential to use water analysis kits, which can be used to measure pH value, free chlorine or oxygen, and total alkali content.
This indicator paper version is used to measure ph, chlorine, bromine, alkali (TA) and water hardness, TH value. It is easy and safe to use.

Indicator paper version, sufficient for 50 measurements.

Usage
The test strip just needs to be dipped in the pool water, then the measuring part at the end of the test strip should be compared with the corresponding part of the color scale on the box.

Based on the color scale, you can easily read the pH value and the free chlorine content of the pool water, so you can keep your pool clean and properly disinfected. If the numbers read from the test strip differ from the indicated ideal value, the pool water must be chemicalized, thereby maintaining the appropriate feeling of comfort and preventing algae growth.

Do not reach into the box with wet hands. Close the tube tightly after removing the strip. For good results, immerse the strip 30-50 cm deep and read in natural light.
Store in a cool dry place.
