Free Chlorine Powder Reagents, DPD Method (100 tests)

Hanna Instruments reagents for the colorimetric determination of free chlorine. Each set contains enough reagent for 100 tests and is used with compatible Hanna portable and benchtop photometers.

They follow the DPD method: the reaction between chlorine and the reagent turns the sample pink, and the photometer measures the intensity and shows the chlorine concentration in mg/L (ppm). They are designed for samples with an expected range of 0.00 to 5.00 mg/L of free chlorine.

• Pre-measured, ready-made reagents for quick and easy use.
• Prepared with high-purity chemicals.
• Lot number and expiry date marked on every packet.
