RYD03-CHL
Digital Chlorophyll Sensor
Product Overview
The RYD03-CHL is a digital chlorophyll-a sensor based on coherent fluorescence detection with excellent selectivity and anti-interference. No sample pretreatment or extraction—non-destructive, reagent-free and pollution-free. An ultra-bright LED improves signal-to-noise; a self-cleaning wiper maintains the measuring face, housed in corrosion-resistant titanium. Ideal for lake/reservoir eutrophication and algae monitoring.
