HI97771-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI97771 portable photometer that has a 0.00 to 5.00 mg/L (ppm) and 0 to 500 mg/L free chlorine range. The HI97771-11 includes one sealed “A” cuvette for zeroing the meter and one “B” cuvette that is used to validate or calibrate. An acceptable reading using the standards with the HI96771 is 1.00 ±0.03 mg/L for the low range and 100 ±3 mg/L chlorine for the ultra high range @ 25℃. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
