Free and Total Chlorine CAL Check Standards for HI97701

HI97710-11 is a high quality set of calibration standards that allows users to validate and calibrate the pH range found in compatible portable photometers that have a 6.5 to 8.5 pH range. The HI96710-11 includes one sealed A cuvette for zeroing the meter and one B cuvette that is used to validate or calibrate. The expected reading from the B standard is pH 7.0 ±0.1 @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
