Hanna HI711-25 Chlorine total DPD method

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.
