饮用水中的游离氯和总氯
饮用水中的游离氯和总氯
Chlorine plays a crucial role in maintaining water quality as it is a predominant chemical disinfectant in water treatment systems. However, in drinking water treatment facilities, it is necessary to assess free and total chlorine levels in greater detail to ensure treatment effectiveness. Also, this helps to prevent the formation of harmful byproducts. To resolve this, Alpha has developed the RC68 Free Chlorine sensor and RC67 Total Chlorine sensor with the following attributes:
Measurement Range Options: Available ranges include 0 – 2 ppm, 0 – 5 ppm, 0 – 10 ppm, 0 – 20 ppm, and 0 – 100 ppm, adjustable within 0 – 100 ppm.
Output Formats: Supports both analog (4 – 20 mA or 0 – 5 V) and digital (RS-485 MODBUS RTU) outputs.
High Accuracy and Resolution: Offers a resolution of 0.01 ppm and an accuracy of 0.2 ppm or 4%, whichever is greater.
