Digital Residual Chlorine Sensor for Water Quality Monitoring
Features
① Three-Electrode Constant Potential Technology
Ensures stable measurements by minimizing polarization effects and interference from pH fluctuations, even in dynamic water conditions.
② Multi-Range Resolution & pH Compensation
Supports resolutions from 0.001 ppm to 0.1 ppm and automatic pH compensation to enhance accuracy in varying water chemistries.
③ Modbus RTU Integration
Pre-configured with default address (0x01) and baud rate (9600 N81), enabling plug-and-play connectivity to industrial automation systems.
④ Robust Design for Harsh Environments
IP68-rated housing and corrosion-resistant electrodes withstand prolonged submersion, high-pressure flows, and temperatures up to 60℃.
⑤ Low Maintenance & Self-Diagnostics
Features automatic zero/slope calibration commands, error code feedback, and optional protective covers to reduce biofouling and manual upkeep.
