HI97715-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI97715 medium range ammonia photometer. The HI97715-11 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 6.0 ±0.2 mg/L ammonia (as NH3-N) @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
