FLDUV254 4-beams Without wiper COD Sensor

Product Name: FLDUV254 4-beams COD Sensor
Product brand：FLUIDINGS

The Fluidings UV254 sensor is an optical-based absorption and transmittance with UV LED and PD technology sensor. The sensor measures the absorption at UV 254nm, blue, green, and red light Simultaneously to compensate the SAC measurement for interferences from turbidity and color.

Features

4 wavelength absorption measurement: UV and Vis
for turbidity and color compensation.
SAC measurement used to determine organic loading
without reagents.
Measurement directly in the process, no sample processing
or reagent required.
Fast response, minimum 10 second.
Cold light source (UV LED) and rugged PD, long life time and
low drift.
Support leakage alarm
