Hanna Instruments CAL Check Standard for Potassium

CalCheck standards for Potassium LR & MR, 0.0 and 5.00 ppm
HI-96750-11 is a high quality set of calibration standards that allows users to validate and calibrate the compatible HI-96750 portable photometers that have a 0.0 to 10.0 mg/L (ppm) potassium range (low range) and 10 to 100 mg/L potassium range (medium range). The HI-96750-11 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 5.0 ±0.5 mg/L potassium @ 25°C for low range and 50 ±5 mg/L potassium @ 25°C for medium range. The calibration set is produced using reagent grade chemicals in a temperature controlled environment.
