Y519-A Self-cleaning CDOM Sensor
Y519-A CDOM sensor adopts the analysis principle of ultraviolet fluorescence method to detect colored soluble organic matter in water. It is suitable for the measurement of colored soluble organic matter in rivers and lakes with high sensitivity and small size. The sensor comes with an automatic cleaning brush that eliminates air bubbles and reduces the impact of contamination on measurements for longer maintenance cycles.
