Description

Introduction:
Gasboard—3200 online infrared biogas analyzer is designed to measure CH4 ,CO2 ,H2S and O2 concentration simultaneously in different biogas applications, like landfill, water treatment and CDM projects anaerobic digestion and other fermentation processes, based on the single source two beams non-dispersion infrared (NDIR) method for CH4 ,CO2 ,fuel electrochemical method (ECD) for H2S and O2, with gidital and analog signal output.
