Water Quality Sensors
RYD03-OIL
Digital Oil-in-Water Sensor
Product Overview
The RYD03-OIL is a digital oil-in-water sensor based on coherent fluorescence detection with excellent selectivity and anti-interference. No sample pretreatment or extraction—non-destructive, reagent-free and pollution-free. Unique optical and electronic filtering eliminates ambient light and is unaffected by suspended particles; self-cleaning keeps it maintenance-free.
