KWS-900 Fiber Optic Turbidity Sensor for Water Quality Monitoring
Introduction
The KWS-900 online turbidity sensor adopts the 90° scattered light measurement principle, complies with international standards, uses customized optical devices, is compact, easy to install and maintain, is not easily disturbed by ambient light, and has better repeatability and stability. In addition, the self-cleaning turbidity meter is equipped with an automatic cleaning brush, which can effectively eliminate the influence of bubbles and contamination on the measurement, making the maintenance cycle longer and maintaining excellent stability even in long-term online use.
Feature
- Digital fiber optic turbidity sensor, RS-485 output, support MODBUS
- With automatic cleaning brush, prevent pollution, eliminate air bubbles
- Strong anti-interference ability, no ambient light and chromaticity
- 90° scattered light principle, better fiber technology repeat-ability
