SH-TUR200 Turbidity digital sensor
Overview
The SH-TUR-200 turbidity digital sensor uses the infrared 90° nephelometric method with its own cleaning brush and has calibration, recording, analysis and diagnostic functions. The sensor adopts RS485 interface and standard Modbus protocol.
Product features
- 90° infrared light scattering method, independent of chromaticity
- Self-cleaning function, remove water samples of adherents and air bubbles, maintenance-free
- Optical and digital filtering technology to eliminate the effects of stray light
- Internal storage of calibration data
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
