MRU OPTIMA 7 Biogas Analyzer simultaneous measurements 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 O2 measurement has a 4-5 year estimated life span. The modern, slim line enclosure features a secure rear-mounted magnet for drop resistant operation.

The engine exhaust model includes all combustion calculations and automatic measurement with user-specific adjustable determination of average value storing on SD card. Also adds 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 includes US landfill gas probe with K-Type t/c input with 6in insertion coiled cable Type K thermocouple and transport case. Gas flow velocity measurement capable using pitot tube, pitot tube is not included. A shoulder strap and spare part set including o-rings, filter, and condensate show glass is also included with all landfill models. The following options only come with the landfill sets that include the H2S gas measurement:

  • 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
