Low Maintenance Of The KWS-850 On-line Multi-parameter Water Quality Sensor

• Digital sensor with RS-485 bus and Modbus/RTU communication protocol
• Automatic cleaning device prevents microorganism attachment for accurate measurements
• Integrated design measures 8 parameters simultaneously (including temperature)
• Optional digital sensors for dissolved oxygen, COD, conductivity/salinity, turbidity, ammonia nitrogen, pH, and ORP
• Ideal for long-term online water quality monitoring

The KWS-850 online multi-parameter water quality sensor features advanced low-maintenance design. Its self-cleaning mechanism uses ultrasonic vibrations or mechanical brushing to remove fouling substances like algae, sediment, or biofilms, ensuring continuous accurate measurements while reducing manual cleaning needs.

Constructed with durable, corrosion-resistant materials, the sensor withstands harsh aquatic environments, including high salinity or chemical impurities, minimizing component replacements. An intelligent diagnostic system monitors performance, detecting issues like electrode malfunctions or signal drops early, alerting operators to prevent downtime.
