HI 96771 has been developed to check chlorine dosing in disinfection processes with ultra high concentrations of chlorine. Thanks to the extended range from 0 to 500 mg/L (ppm), it is ideal for the food industry, such as in fruit and vegetable washing.The HI 96771 meter measures the free chlorine (Cl2) from 0- 5 ppm content in water and total chlorine in the ultra high range 0-500 ppm. The methods are an adaptation of Standard Methods for the Examination of Water and Wastewater, 20th edition, 4500-Cl.The meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results.Specifications:

  • Free Chlorine range: 0.00 to 5.00mg/L (+/-0.03mg/l)
  • UHR Chlorine (total) range: 0.00 to 5.00mg/L (+/-3mg/l & +/-3% of reading)Supplied with:
  • Sample cuvettes and caps x2 each
