The HI96750-11 Potassium Standards (CAL Check™ ) provide a simple solution to calibrating and validating the compatible HI96750 Potassium Portable Photometer. This high quality set of standards is manufactured in our state-of-the-art facility and comes supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying compatible potassium photometers
Supplied with Certificate of Analysis
Standard value of 5.0 ±0.5 mg/L potassium (low range) @ 25oC
Standard value of 50 ±5 mg/L potassium (medium range) @ 25oC
HI96750-11 is a high quality set of calibration standards that allows users to validate and calibrate the compatible HI96750 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 HI96750-11 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. The HI96700-11 is supplied with Certificate of Analysis
