เครื่องวัดคลอรีน Colorimeter Chlorine Meter - เครื่องวัดคลอรีน อิสระ Free Chlorine Meter HI-95771C
HI 95771 is a photometer developed to check chlorine dosing in disinfection processes with high concentrations of chlorine. Thanks to the extended range from 0 to 500 ppm, it is ideal for the food industry, such as in fruit and vegetable washing.
HI 95711 also offers an additional range (0.00 to 5.00 ppm) for accurate measurements at lower values, to help control the chlorine level before discharging the treated water.
Finally, instrument validation is possible at any time with Cal Check standard cuvets.
