REF 91361 Package: unit 50 Test(s)Semi-quantitative test strips for reliable determination of total chlorine concentrations as low as 0.01 mg/L (ppm). A hole in the plastic carrier allows the water to migrate through the test pad, providing a high level of sensitivity. Ideal for rapid and easy analysis of total chlorine directly on-site. No maintenance or calibration is required.

General information
Chlorine (Cl2) is used as a highly effective disinfectant for example in drinking and swimming pool water.
The test strips QUANTOFIX® Total Chlorine Sensitive 1 allow for reliable determination of chlorine concentrations as low as
0.01 mg/L (ppm) which usually requires colorimetric or photometric analysis. A hole in the plastic carrier allows the water to
migrate through the test pad, providing a high level of sensitivity.
Reaction principle
Chlorine and chlorine-containing substances react with an organic redox indicator to form a blue-green oxidation product.
