- Prepared with high purity chemicals
For use with the Hanna HI-38017 colour wheel checker disc these are a set of 200 replacement reagents for Chlorine Free & Total low range and medium range.
Use these reagents to measure Free and Total Chlorine in the ranges 0.00 to 0.07mg/L (ppm) low range and 0 to 3.5mg/L(ppm) medium range.
The HI-38017-200 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate free and total chlorine measurements with the chemical test kit. These reagents follow the DPD (N,N-diethyl-p-phenylenediamine) method to determine free and total chlorine concentration.
For determination of free and total chlorine, the appropriate 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 and total chlorine concentration. These reagents are designed to be used with low range samples that have an expected free and total chlorine range of 0.00 to 0.70 mg/L (ppm) Cl2 and high range samples that have an expected range of 0.0 to 3.5 mg/L (ppm) Cl2.
