Small Low Power Modbus RTU Integrated Self-Clean Chlorine Sensor for Swimming Pool

The three-electrode system maintains a stable potential at the measuring electrode, significantly reducing the influence of pH fluctuations on chlorine readings.

Advanced membrane-free constant potential sensing removes the need for electrolyte refilling or membrane swaps, cutting recurring maintenance costs and downtime.

The integrated model uses a double salt bridge reference electrode design, providing stronger resistance to contamination from complex water matrices than standard single-bridge reference electrodes.

Three measurement ranges cover drinking water compliance monitoring at low concentrations up to industrial wastewater disinfection control at higher chlorine dosing levels.

Consistent repeatability of plus or minus 0.05 mg/L ensures reliable trend monitoring and process control without recalibration between sequential measurements in dosing systems.

Sub-30-second response enables tight feedback loops in automatic chlorination systems for swimming pools, drinking water plants, and industrial circulating cooling water applications.

Electrode sensing surface is made from high-purity platinum, resisting corrosion and physical wear during continuous submersion, supporting a rated electrode service life of approximately one year.

RS-CL-2 industrial variant outputs RS485, 4 to 20mA, 0 to 5V, 0 to 10V, and LoRaH, enabling both wired SCADA integration and long-range wireless telemetry from remote monitoring points.

Integrated sensor is rated IP68 for full submersion, while the industrial-grade data collector is IP65-rated for outdoor enclosure use, covering both immersed and panel-mounted installation scenarios.

Each unit ships factory-calibrated and ready for immediate use. On-site recalibration is only recommended when readings are confirmed inaccurate.
