Hanna HI3875-100 Chlorine free MR DPD colorimetric method

Hanna HI3875-100 Chlorine free MR DPD colorimetric method

The Hanna HI3875-100 Chlorine free MR DPD colorimetric method is a high-quality replacement reagent pack designed for use with the HI3875 Free Chlorine Test Kit. This kit allows users to measure free chlorine concentrations in water samples using the DPD (N,N-diethyl-p-phenylenediamine) colorimetric method, a trusted standard in water quality analysis.

Each pack contains enough reagents for approximately 100 tests, making it ideal for frequent monitoring in water treatment, environmental labs, pools, and educational use. Results are measured visually using a color comparator, with a detection range from 0.0 to 3.5 mg/L.
