Online Cyanobacteria Sensor
The S‑BGA121 Online Cyanobacteria Sensor is an online water quality analyzer developed based on the Links optical water quality analysis platform. Its highly sensitive photodetector captures faint fluorescent signals and converts them into algal density measurements.
Designed with a digital and intelligent sensor architecture, it automatically compensates for the effects of voltage fluctuations, device aging, and temperature changes on measurement values. With RS485 signal output, it facilitates networking and system integration and is widely used in industries such as surface water monitoring.
