SH-BGA200 Blue-Green Algae digital sensor
Overview
SH-BGA-200 Blue-Green Algae digital sensor adopts specific wavelength and high brightness monochromatic light to stimulate algal blue protein to emit fluorescence, and receives its fluorescence signal through highly sensitive photoelectric sensor, and obtains the density of blue-green algae in the water body according to the proportionality relationship between fluorescence intensity and algal density. The device has digital intelligent design, adopts RS485 interface and standard Modbus protocol, comes with cleaning brush and temperature compensation, and has the functions of calibration, recording, analysis and diagnosis.
Product features
- Self-cleaning function removes light window stains and air bubbles, maintenance-free
- Optical and digital filtering technology to eliminate the influence of stray light
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
