Water Quality Online Monitor

Online multi-parameter water quality detector is an instrument that can measure multiple water quality parameters at the same time. It integrates multiple sensors and measurement module communication storage, and can quickly and accurately record multiple key parameters in the water body. Including but not limited to pH value, dissolved oxygen (DO), conductivity, turbidity, temperature, ammonia nitrogen, etc., can be combined and configured according to different needs and applications, record and store historical monitoring data, alarm history records, and support historical data export.xlsx. The RS485 interface supports MODBUS-RTU communication protocol to facilitate users to freely communicate with PLC, DCS, configuration software, DTU and other devices to connect and transmit data.
