Case analyzer chlorine free/total CHECKIT

Checkit Comparator 

It is a compact and easy to use colorimetric system. It analyzes the free and total chlorine levels of the pool water through a disc with a color graduation.

This test kit is perfect for residential pools and spas for daily or weekly monitoring of pool chlorine levels. This kit is composed of fast dissolving DPD tablets to test free chlorine and total chlorine. 

This comparator is based on a disc with a continuous color graduation, allowing an exact chromatic match between the color standard and the aqueous test. Thanks to the careful selection of materials and optimized manufacturing, the discs will remain color stable over a long period of time, ensuring reliable and reproducible results.

The disc has a scale of 0 to 1 mg/l and provides high accuracy of analysis. The accuracy of the disc is ± 5% final value.
