Ammonia Low Range CAL Check Standard

HI97700-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI96700 Ammonia Low Range photometer. The HI97700-11 includes one sealed A cuvette for zeroing the meter and one B cuvette that is used to validate or calibrate. The standard value of the B cuvette is 1.50 ±0.01 mg/L (ppm) ammonia nitrogen (NH3-N). An acceptable reading when validating the HI96700 with the standards is 1.50 ±0.05 mg/L @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment. CAL Check" standards with certificate The HI97700-11 CAL Check"standards are used for calibration and performance verification of HI977 photometers with the CAL CheckTM function.
