Product Overview
Description
Features Of COD Sensor
● Use UV254 nano-ultraviolet absorption measurement method,require no consumable；
● Use two light sources, 254nm and 365nm UV reference light；
● Automatically eliminate the interference of suspended solids and compensate for the interference of turbidity;
● Can measure parameters such as COD, TOC, turbidity and temperature；
● Drop-in installation, no need to digest the tested sample, fast analysis speed, real-time response, no need to wait；
● RS485 digital interface, standard Modbus communication protocol, support access to standard industrial control system；
● Haveexcellent repeatability and stability, and is not easily affected by ambient light；
● Integrated self-cleaning brush, small size and convenient to install, continuouslymonitor water quality online to prevent biological attachment andreduce the frequency of maintenance.
