Gasboard 3200 infrared biogas analyzer can be used for measurement of the concentration of CH4, CO2, H2S and O2Cubic Online NDIR Biogas Analyzer

Gasboard 3200 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 19 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.


  • 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
  • 320*240 LCD with menu operation.
  • Repeatability: ±0.5% FS
  • Linearity: ±1% FS
  • Zero/Span drift: ±2%FS


 Resolution     Precision Error
CO2 NDIR 50% 0.01% ≤2% FS ≤2%
CH4 NDIR 100% 0.01% ≤2% FS ≤2%
H2S ECD 9999PPM 1PPM ≤3% FS ≤2%
O2 ECD 25% 0.01% ≤3% FS ≤2%
