Calcium Hardness CAL Check Standards

HI96720-11 is a high quality set of calibration standards that allows users to validate and calibrate the calcium hardness range found in the compatible HI96720 portable photometer that has a 0.00 to 2.70 mg/L (ppm) CaCO₃ range. The HI96720-11 includes one sealed "Ain. cuvette for zeroing the meter and one "Bin. cuvette that is used to validate or calibrate. The expected reading from the "Bin. standard is 1.50 ±0.07 mg/L CaCO₃ @ 25^°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
