Suspended Solid Sensor

BH512-A suspended solid sensor measures 135 degree backscattering light from particulates in water. The self-cleaning wiper ensures high clarity of the optical window from biofouling, air bubbles, and particle deposition. The high sensitivity sensor provides a cost effective solution for in-situ environmental, wastewater monitoring and process control.

Features

MODBUS RS485 interface
Auto cleaning wiper
High ambient light rejection
Low power consumption and low maintenance
