RS485 WIFI Digital COD Analyzer UV254nm Sensor For Measurement Of Water COD
Brief Introduction Of The COD Analyzer
The Daruifuno's COD analyzer includes a controller and a sensor, the chemical oxygen demand controller is specially designed for the measurement of the COD in water.
The principle of the matched COD sensor is Spectral Absorption Coefficient (SAC), by measuring the degree of absorption of ultraviolet light with a wavelength of 254 nm by organic substances, the substitution of organic substances in water can be detected.
Advantages Of The COD Analyzer
Menu password of the COD controller can be set to facilitate user's data confidentiality;
The COD meter has time and historical data recording functions to meet higher data management requirements;
The COD instrument has a 3.2-inch display screen and it has power-off protection configuration, and the parameters can be kept indefinitely;
For the COD sensor UV351, it can measure COD, TOC, turbidity, temperature and other parameters; consumables are not required during the measurement process;
The sensor can automatically eliminate the interference of suspended solids and compensate for the interference of turbidity.
Applications Of The COD Analyzer
- Monitoring for compliance
- Optimization of wastewater treatment processes
- Development of process control algorithms
- Identification of cross-connected sewers
- Identification of pollution sources
- Rapid assessment of incident severity
- Advanced treatment monitoring & protection
- Effluent pollution
