Infrared Biogas Analyzer

详情

Introduction: Gasboard ***0 infrared biogas analyzer can be used for measurement of the concentration of CH4, CO2, H2S and O2 in sample gases simultaneously . It is based on the single source two beams non-dispersion infrared (NDIR) method for CH4, CO2, fuel cell method (ECD) for H2S and O2. This analyzer is designed with *9 inches 3U smaller physical dimensions and the simple digital pulsable infrared source and two beam systems. The general application is landfill, anaerobic digestion and other. Features: Up to 4 gases measurement with combination of NDIR and ECD gas sensor technology Simple construction with pulsable infrared source and two beams technology Constant temperature control for gas bench for high stability **0***0 LCD with menu operation.
