Hanna (HI93701-03) Reagent Kit - 300 Tests; Chlorine Free
HI93701-03 Free Chlorine Reagent Kit
The HI93701-03 reagent kit delivers 300 high-quality, pre-measured tablets designed for fast and accurate free chlorine measurements using the DPD colorimetric method. Each tablet reacts with chlorine in your sample to produce a pink tint proportional to chlorine concentration, eliminating the guesswork of liquid reagent dosing and ensuring consistent results across all 300 tests.
DPD Colorimetric Analysis
Collect Water Sample
Fill your test vial or cuvette with the water sample you need to analyze for free chlorine content. The HI93701-03 is calibrated for samples expected to contain between 0.00 and 5.00 mg/L free chlorine.
Add DPD Reagent Tablet
Drop one pre-measured HI93701-03 tablet into your sample. The DPD reagent reacts with free chlorine to produce a pink tint, with color intensity directly proportional to chlorine concentration.
Read Results
Insert the sample into your compatible Hanna colorimeter or photometer. The meter reads the color intensity and displays the free chlorine concentration in mg/L (ppm) on the digital screen.
Works With Hanna Colorimeters and Photometers
The HI93701-03 reagent tablets are designed for use with Hanna Instruments benchtop and portable colorimeters that support free chlorine testing via the DPD method. Check your meter's documentation to confirm compatibility with the HI93701 series reagents. Each kit provides 300 tests, making it ideal for laboratories, water treatment facilities, pool service professionals, and quality control applications requiring frequent chlorine monitoring.
