Calibration of the HI97771 Photometer's ultra high chlorine range is quick and easy with the HI97771-11 CAL Check Standards.
These standards provide a simple solution to calibrating the photometer. They are reusable and include one sealed “A” cuvette for zeroing the meter and one “B” cuvette used to validate. The HI97771-11 standards work with the HI97771 UHR Photometer to check the 0 to 500 mg/L (ppm) ultra high chlorine range.
Hanna’s exclusive CAL Check feature provides a stress-free, straightforward way to ensure your photometer is working properly. Simply insert the certified standards and let your meter guide you through validation. If your photometer is out of specification for any reason, simply calibrate to the standard.
