Online CDOM/FDOM sensor
Key specifications:
✅Range 0-400ppb (Customisable)
✅RS485,MODBUS protocol
✅Ultraviolet fluorescence method
✅Easy on-site use
✅Self-cleaning system
Online CDOM (Colored Dissolved Organic Matter) sensor is a fluorescent sensor that detects the fluorescent components of dissolved organic matter under near-ultraviolet light; it is also known as an FDOM (Fluorescent Dissolved Organic Matter) sensor. This method directly measures the fluorescence intensity emitted by CDOM/FDOM when excited by ultraviolet light to determine the relative concentrations of CDOM and FDOM.
Product Features
✅Digital sensor, RS485 output, standard MODBUS protocol.
✅Advanced fluorescence sensing technology,strong anti-interference ability, reduce the influence of light and chromaticity.
✅Self-cleaning brush to prevent microorganisms from adhering to the sensor and prolong the maintenance cycle.
✅Built-in calibration parameters, convenient for field use and secondary calibration
