HI-97710-11 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 HI-97710-11 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 and manufactured using grade chemicals in a temperature controlled environment.
The HI-97710-11 CAL Check standards are used for calibration and performance verification of HI-977 photometers with the CAL Check function.
