Y519-A Self-cleaning CDOM Sensor
Yosemitech Y519-A CDOM sensor adopts ultraviolet fluorescence technology to detect colored dissolved organic matter (CDOM) in water. Due to its high sensitivity and compact design, it is particularly well-suited for measuring such substances in rivers and lakes. The sensor features an integrated cleaning brush, which effectively removes bubbles, minimizes contamination effects on measurements, and extends the maintenance interval. Additionally, it ensures exceptional stability for long-term online monitoring.
- Digital sensor with RS485 output and support for the standard MODBUS protocol.
- Utilizes ultraviolet fluorescence analysis, specifically designed for detecting colored soluble organic matter in water.
- Capable of measuring seawater and high-salinity samples while requiring minimal maintenance.
- Equipped with a cleaning brush to prevent microbial attachment and extend the maintenance interval.
- Includes built-in calibration parameters for convenient on-site use and secondary recalibration.
