The MRU OPTIMAX Biogas Analyzer can simultaneously measures of up to 7 gas components. The biogas measurements include O2, H2S, CH4 and CO2 (infrared for CO2/CH4). The emissions measurements include O2, CO, NO, NO2 and CO2.

The biogas and engine exhaust models includes all combustion calculations and automatic measurement with user-specific adjustable determination of average value storing on SD card. These models also add the following accessories:

  • Gas sampling probe for exhaust gas emission monitoring with 9ft Viton hose
  • 12in probe tube
  • Heat deflector
  • Transport case

The landfill model provides gas flow velocity measurement capable using Pitot tube (not included). It includes a US landfill gas probe with K-Type t/c input with 6in insertion cable, Type K thermocouple with 6in insertion cable, and transport case. All landfill models include a spare part set (O-rings, filter, and condensate show glass).

Landfill models with H2S gas measurement option also include the following:

  • HC "sniffer" for gas leakage detection with 1.5 meter cable and swan neck
  • AUX universal auxiliary port - connection for external gas sniffer
  • Auto data logging function





Please consider these optional accessories.
