Digital BOD, TOC ,Turbidity COD Sensor For Water Treatment Plant Measuring
Many organic substances dissolved in water absorb ultraviolet light. Therefore, by measuring the degree of absorption of 254nm wavelength ultraviolet light by these organic substances, the content of dissolved organic pollutants in water can be accurately measured.

Brief introduction:
● 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
