Product description:
TracWater TW-4765B/C COD sensor features highly reliable UVC LED for light absorption measurement. Automatically compensates for turbidity interference and has excellent test performance. Low cost and low maintenance.

Overview

TracWater TW-4765B/C COD sensors adopt the UV absorption technology to accurately quantify dissolved organic contaminants in water. It measures the absorption of organic molecules at a wavelength of 254 nm using UV light. The sensors feature an integrated turbidity detection light source that automatically compensates for turbidity interference in water samples. Additionally, it is equipped with a self-cleaning brush, ensuring excellent stability during long-term online monitoring.

Features

  • Requires no reagents, ensuring pollution-free operation, and offering a more economical and environmentally friendly solution.

​

  • Capable of measuring multiple parameters, including COD, TOC, turbidity, and temperature.

​

  • Features automatic compensation for turbidity interference.

​

  • Equipped with a self-cleaning brush that effectively prevents microbial adhesion, significantly extending the maintenance cycle.

​

  • Includes calibration parameters to facilitate on-site and secondary calibration processes.
