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
Aplication:
◇ Surface water
◇ Process water
◇ Sewage treatment plant
◇ Industrial wastewater
◇ Drinking water
◇ River
