Hanna HI711-25 Chlorine total DPD method
The Hanna HI711-25 contains high-quality, pre-measured reagents specially designed for use with the HI711 Total Chlorine Checker. These reagents use the DPD (N,N-diethyl-p-phenylenediamine) method, in which chlorine reacts with the reagent to produce a distinct pink color. The intensity of this color is measured by the Checker HC and converted into a precise total chlorine reading, displayed in ppm (mg/L).
Perfect for both laboratory and field testing, the HI711-25 simplifies chlorine testing by eliminating preparation steps and ensuring reliable, accurate results every time.

Best Practice Tips for Accurate Results
Ensure the sample is free of debris before testing.
Always clean the cuvette’s outer surface to remove fingerprints or residues using a lint-free cloth (e.g., HI-731318).
Avoid shaking the cuvette—gently swirl or tap to eliminate bubbles.
Read the result immediately after mixing—delayed readings can lead to inaccurate results.
Dispose of the sample after testing to prevent staining of the cuvette glass.
