Biogas analyzers
ZPAF Biogas Analyzer & ZPSB Biogas Analysis System
High-stability and ease-of-maintenance incorporated in a space-saving design
Biogas is a mixture of methane and carbon dioxide with a few other components. It is used for the production of heat, electricity or biofuel.
ZPAF biogas analyzer can simultaneously and continuously measure the concentration of CH4, CO2, H2S and O2components in the biogas :
- CH4 and CO2 are measured by non-dispersive infrared method (NDIR)
- O2 : Electrochemical fuel cell – life time > 2 years
- H2S : Constant potential electrolytic sensor – life time > 1 year
ZPAF biogas analyzer can be integrated to the ZPSB Biogas Analysis System.
This full cabinet allows reliable, robust and efficient biogas and H2S measurement up to really high content.
