Spectral COD online analyzer

Instrument Overview:

The UV COD online analyzer can achieve rapid, accurate, and economical online determination of COD in water samples. The basic measurement principle of the instrument is based on the absorption of ultraviolet radiation by organic matter in wastewater. Organic compounds containing conjugated double bonds or polycyclic aromatic hydrocarbons absorb ultraviolet light when dissolved in water. Therefore, by measuring the absorption of ultraviolet light by these organic compounds, we can evaluate the degree of water pollution caused by these organic compounds.

Application scope:

The application areas include drinking water, surface water, industrial process water, sewage treatment, and other fields. It can be used for continuous monitoring of the degree of organic pollution in raw water, sewage plant imports, and the removal rate of organic matter during the treatment process, as well as the degree of organic pollution in industrial circulating water.

Key Features:

1.The water sample pretreatment device adopts a maintenance free design, which can ensure that the maintenance cycle of the pretreatment device exceeds six months.

The measurement process is completed in an instant, and the measurement process and results meet relevant international standards.

3. The fully imported components and innovative analysis flow path design ensure measurement reproducibility, which can currently reach 3%.

4. Fully automatic operation, no need for personnel on duty, can achieve intelligent functions such as automatic zero adjustment, automatic calibration, automatic measurement, automatic cleaning, automatic maintenance, self-protection, and automatic recovery.

5. The online monitoring methods are diverse, allowing for manual measurement at any time, automatic timed measurement, automatic periodic measurement, and other measurement methods.

6. No chemical reagents are required, no secondary pollution is generated, and true real-time online monitoring of COD is achieved.
