Multi-parameter Water Quality Probe Is Equipped With An Automatic Cleaning Device, Featuring A Low Maintenance Cycle, High Stability And Accuracy
1.Overview
The multi-parameter water quality sensor is designed for freshwater applications such as groundwater and surface water. It can be fixedly installed with multiple water quality sensors (monitoring factors: water level, temperature, pH, ORP, conductivity, TDS, dissolved oxygen, turbidity, oil in water, ammonium ions, potassium ions, nitrate, chloride ions, fluoride ions, etc.). It adopts RS485 interface and standard Modbus protocol, with low power consumption. Data analysis software is randomly included, featuring functions such as calibration, recording, analysis, and diagnosis.
