Digital RS485 Interface Modbus COD/TOC/BOD Controller For Treated Water
DRFN water quality online analyzer can realize automatic online monitoring of chemical oxygen demand in water samples. The monitoring data and operating status of the instrument can be transmitted to the environmental monitoring and control center through the data acquisition instrument; the environmental monitoring and control center can also send counter-control instructions to control the instrument to complete the measurement, calibration and other processes. DRFN series instruments can be widely used in automatic monitoring stations, water plants, regional water boundary points, heavy metal monitoring of water quality in sewage discharge, and monitoring of water environment by environmental regulatory agencies at all levels.
