Introduction
Gasboard-3200 online biogas analyzer is designed to measure CH4, CO2, H2S and O2 concentration simultaneously in different biogas applications, like landfill, water treatment, CDM projects, anaerobic digestion and other fermentation processes, based on NDIR technology for CH4 ,CO2 gases and ECD technology for H2S and O2 gases.
Applications
Landfill site
Waste water treatment
Bio-methane plant
CDM project
Anaerobic digestion
OEM biogas monitoring system integrating
