Product Overview

The SX-CHUCA Series self-cleaning COD sensor is based on the UV absorption method. It measures the absorption of 254 nm ultraviolet light by dissolved organic matter to determine the concentration of dissolved organic pollutants in water. The sensor requires no reagents and generates no chemical waste, making it a cost-effective and environmentally friendly solution. An integrated turbidity-detection light source provides automatic turbidity compensation, while the automatic cleaning brush helps maintain stable long-term performance during continuous monitoring.

Main Features

  • No reagents required; pollution-free; more economical and environmentally friendly
  • Measures COD, TOC, turbidity, and temperature
  • Automatic turbidity compensation for reliable measurement performance
  • Equipped with self-cleaning brush to prevent biofouling, extending maintenance interva
  • Built-in calibration parameters for convenient field use and recalibration
