EmailThe ZDU-02 Turbidity Sensor is a kind of intelligent turbidity electrode adopting RS485 communication interface and standard Modbus protocol. It can be widely applied to turbidity monitoring in sewage plants, waterworks, surface water and industries, etc.
Features
With corrosion resistant shell and IP68, applicable to all kinds of poor working conditions
Use infrared LED of 850nm wavelength as light source, not affected by chromaticity of water sample; adopt 90° Scattering Method; meet standards of NFEN872 and NFT901052
Digital Modulation Filtering Technique eliminates influence of ambient light.
Bubble compensation algorithm reduces bubble interference in the water sample
Infrared LED light source with long service life, up to 10 years or above
Automatic range (high/medium/low) switching improves measurement accuracy
Use RS485 communication interface and standard Modbus protocol, convenient for integration
