RYD03-BGA
Digital Blue-Green Algae Sensor
Product Overview
The RYD03-BGA is a digital blue-green algae (phytocyanin density) sensor based on coherent fluorescence detection with excellent selectivity and anti-interference. Reagent-free and pollution-free; an ultra-bright LED improves signal-to-noise and stability. Self-cleaning removes fouling periodically for maintenance-free operation—ideal for cyanobacteria early warning and bloom monitoring.
