The HI97728-11 Nitrate CAL Check™ standards provide a simple solution to calibrating and validating the HI97728 Nitrate Portable Photometer that has a 0.0 to 30.0 mg/L (ppm) range of nitrate-nitrogen. 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 the HI97728 photometer.
Supplied with Certificate of Analysis
Standard value of 15 ±0.050 mg/L (ppm) nitrate-nitrogen @ 25°C
HI97728-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI97728 Nitrate Photometer that has a 0.0 to 30.0 mg/L (ppm) nitrate-nitrogen range. The HI97728-11 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 15.0 ±1.0 mg/L nitrate-nitrogen @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
