Product Description

High-Sensitivity Water Quality Tester Meter Wastewater Treatment Turbidity Meter Industrial Online Turbidity 

Product Description


Our turbidity sensors use fiber optic technology to provide superior repeatability and stability, and are less susceptible to ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of contamination on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.
* Digital sensor, RS-485 output, support MODBUS
* With automatic cleaning brush to prevent contamination and eliminate air bubbles
* Strong anti-interference ability, free from ambient light and chromaticity
* 90° scattered light principle, with fiber optic technology for better repeatability
