ZWQ-TUB1 Turbidity Sensor
ZWQ-TUB1
The ZWQ-TUB1 measures water turbidity from 0-1000 NTU using optical scattering with an 850 nm infrared LED light source. It has a self-cleaning function and a titanium alloy body with a sapphire optical fibre, and communicates over RS485 Modbus RTU. MetSensor UK supplies the ZWQ-TUB1 in the UK as part of the Zata IoT sensor range.
