The MI509-100 pH liquid reagent kit includes high-quality reagents that are ready-to-use with Milwaukee's pH, Free & Total Chlorine photometer MI411. The reagents and the meter use the adaptation of USEPA Method 330.5 and Standard Method 4500- CL G & adaptation of the phenol red method. 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 6.5 to 8.00 pH.
