Range: 0.00 to 5.00 mg/L (ppm)
Standard value of 1.00 ±0.01 mg/L (ppm) free chlorine @ 25°C
HI96701-11 is a high quality set of calibration standards that allows users to validate and calibrate the compatible free chlorine portable photometers that have a 0.00 to 5.00 mg/L (ppm) range. The HI96701-11 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 1.00 ±0.03 mg/L free chlorine @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
