Features
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;
Have excellent repeatability and stability, and is not easily affected by ambient light;
integrated self-cleaning brush, small size and convenient to install, continuously monitor water quality online to prevent biological attachment and reduce the frequency of maintenance.
