KWS-850 Online Multi-Parameter Water Quality Sensor with RS-485 Modbus/RTU, Automatic Cleaning, and ±0.1pH Accuracy
The KWS-850 online multi-parameter water quality sensor features exceptional low-maintenance characteristics that distinguish it in the market. Its self-cleaning mechanism utilizes ultrasonic vibrations or mechanical brushing to effectively remove fouling substances such as algae, sediment, or biofilms that accumulate on the sensor surface. This ensures continuous accurate measurements while significantly reducing manual cleaning requirements.
Constructed with durable, corrosion-resistant materials, the sensor withstands harsh aquatic environments, including those with high salinity or chemical impurities. This durability minimizes component replacements and repairs. The integrated intelligent diagnostic system continuously monitors sensor performance, detecting potential issues early and alerting operators promptly to minimize downtime and maintenance efforts.
