The MI511-100 Free & Total Chlorine & pH liquid reagent kit includes high-quality reagents that are ready-to-use with Milwaukee's Free & Total Chlorine, pH Meter MI411. The reagents use the DPD Method with a reaction between chlorine and reagent causing a pink tint in the sample. Simply add the reagent to the sample, wait for the reaction to take place and the photometer determines the concentration based on the color. The reagents are designed for use with samples that have an expected range of 0.00 to 5.00 ppm (mg/L) Free & Total Chlorine and 6.5 to 8.0 pH range.
