Hanna (HI93701-01) Reagent Kit - 100 Tests; Chlorine Free
HI93701-01 Free Chlorine Reagent Kit
The Hanna HI93701-01 reagent kit delivers laboratory-grade accuracy for free chlorine testing in pool, spa, and drinking water applications. Each packet contains pre-measured DPD powder that reacts with free chlorine to produce a pink tint, with color intensity measured by compatible Hanna photometers to display precise mg/L concentration.
DPD Colorimetric Testing Process
Water Sample Collection
Collect water sample in clean cuvette or sample cell compatible with your Hanna photometer
Add DPD Powder
Add one pre-measured HI93701-01 reagent packet to sample and mix thoroughly until powder dissolves
Color Development
Free chlorine reacts with DPD to produce pink coloration, with intensity proportional to chlorine concentration
Photometric Analysis
Insert sample into Hanna photometer for optical reading and digital display of free chlorine in mg/L or ppm
Works With Hanna Photometers
The HI93701-01 reagent kit is designed for use with Hanna Instruments colorimetric photometers that support free chlorine testing via the DPD method. Ideal for pool and spa professionals, water treatment facilities, and drinking water monitoring applications where accurate free chlorine measurement between 0.00 and 5.00 mg/L is required. Each kit contains 100 individual powder reagent packets for consistent, repeatable results without the need for liquid reagents or manual measurement.
