Standardele CAL Check™ pentru potasiu LR și MR, 0,0 și 5,00 ppm, recomandat la HI97750

HI97750-11 is a high quality set of calibration standards that allows users to validate and calibrate the compatible HI97750 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 HI97750-11 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 in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
