Description:
Digital blue-green algae sensor, a digital sensor developed based on the fluorescence optical water quality analysis platform. The sensor uses a specific wavelength high-brightness LED light to excite the blue-green algae in the water sample. The phycocyanin or phycoerythrin in the blue-green algae will emit fluorescence. The high-sensitivity photoelectric sensor in the analyzer will capture the weak fluorescence signal and convert it into a blue-green algae concentration value. The sensor has RS485 output, standard MODBUS protocol, and supports various terminal networking.
Features:
Fluorescence optical method
On-site plug and play
Excellent repeatability and stability
Not easily affected by ambient light
No reagents required, low maintenance
Internally store calibration data, support offline calibration
RS485 digital interface, Modbus communication protocol
