JW-ZS-206(K07) Online Turbidity Sensor is designed for continuous turbidity measurement in drinking water, surface water, wastewater treatment, industrial process water, tanks, pipelines, and environmental monitoring systems. Based on the 90° scattered light principle with a stable infrared LED source, the sensor delivers reliable turbidity and temperature data through RS485 Modbus RTU communication. Its IP68 waterproof structure supports long term submerged installation for smart water quality
2. Product Overview
JW-ZS-206(K07)online turbidity sensor is engineered for continuous monitoring of suspended particles and water clarity in industrial and environmental water systems. It uses a 90° scattered light method: when light enters the water sample, suspended turbidity particles scatter the beam, and the sensor calculates turbidity by measuring the scattered light intensity perpendicular to the incident light.
With RS485 Modbus RTU communication, the sensor can be easily connected to industrial control systems, smart water platforms, data acquisition terminals, and remote telemetry units. Its compact integrated design, IP68 protection, and 3/4 NPT installation thread make it suitable for long term online monitoring in tanks, pipelines, reservoirs, treatment plants, and outdoor water monitoring stations.

3. Application Scenarios
Drinking Water Monitoring: Suitable for continuous turbidity monitoring in drinking water treatment, clean water tanks, and water supply networks.
Surface Water Monitoring: Can be used in rivers, lakes, reservoirs, canals, and environmental monitoring stations to track changes in water clarity.
Wastewater Treatment: Useful for turbidity monitoring in treatment tanks, discharge outlets, aeration systems, sedimentation tanks, and process control points.
Industrial Process Water: Supports turbidity measurement in industrial water circulation, filtration systems, cooling water, and production water treatment.
Smart Water IoT Systems: The RS485 Modbus RTU output makes the sensor easy to integrate with telemetry terminals, gateways, cloud dashboards, and remote alarm systems.
4. Installation Notes
The sensor supports submerged installation with a 3/4 NPT thread. During installation, the sensor should maintain a distance of more than 5 cm from the side wall and more than 10 cm from the bottom to reduce measurement interference. Cable joints should be waterproofed, especially when the sensor is used in long term submerged environments or exposed outdoor applications.
5. Maintenance Guide
The measuring window must remain clean to maintain accurate readings. The sensor surface can be cleaned with tap water. If debris remains, wipe it gently with a damp soft cloth. For stubborn contamination, a small amount of household detergent may be added to water for cleaning. Avoid strong mechanical impact because the sensor contains sensitive optical and electronic components.
