COD Analyzer / BOD Analyzer / TOC Analyzer
The measuring principle is based on the UV light absorption by unsaturated organic molecules at 254nm according to the Beer-Lambert law:
[C]= k log (Iin/Iout)
With
[C]: sample concentration
k: absorption coefficient (specific to each molecule)
Iin: light intensity at the input of the sample
Iout: light intensity at the output of the sample
- Multi-language
- 10 Years lamp lifetime
- No filtering with river water or wastewater
- Multiplexing configuration
- Automatic cleaning system
- Explosion proof (Option)

For River Water
The applications concern mainly river monitoring for environmental studies and drinking water treatment plants.
Successful and cost-efficient applications are also reported on automatic coagulant dozing.
For Wastewater
The COD Analyzer of the final effluent is a critical parameter for environmental requirements on many chemical and food industries. A fast and reliable on-line measuring system is needed.
