Total Hardness CAL Check™ Standards - HI97735-11

HI97735-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI97735 Total Hardness EPA Portable Photometer that has a full range of 0 to 750 mg/L (ppm) CaCO₃. The HI97735-11 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 150 ±10 (low range), 350 ±15 (medium range), and 520 ±20 (high range) 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.
