There are enough reagents for approximately 200 tests to be used with Hanna’s test kit. These high quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.

  • Pre-made reagents for ease of use
  • Prepared with high purity chemicals

The HI-38018-200 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate free chlorine measurements with the chemical test kit. These reagents follow the DPD (N,N-diethyl-p-phenylenediamine) method to determine free chlorine concentration.

For determination of free chlorine, the DPD powder reagent is added to a sample containing chlorine. The reaction between chlorine and the reagent causes a pink coloured complex to form; the greater the concentration, the deeper the colour. A Checker Disc is included for an accurate, side-by-side, visual analysis to determine free chlorine concentration. These reagents are designed to be used with low range samples that have an expected free chlorine range of 0.00 to 0.70 mg/L (ppm) Cl2 and high range samples that have an expected free chlorine range of 0.0 to 3.5 mg/L (ppm) Cl2.
