The Landtec GEM5000 is the next generation in the GEM Series of LANDTEC instruments for accurate measurement and monitoring of landfills.


  • Measures % CH4, CO2 and O2 Volume, static pressure and differential pressure
  • Calculates balance gas, flow (SCFM) and calorific value (KW or BTU)
  • High Accuracy and Fast Response Time
  • Lighter and More Compact
  • Annual recommended factory service
  • Certified intrinsically safe for landfill use
  • Calibrated to ISO/IEC 17025


  • Designed specifically for use on landfills to monitor landfill gas (LFG) extraction systems, flares, and migration control systems.
  • No need to take more than one instrument to site.
  • Can be used for monitoring subsurface migration probes and for measuring gas composition, pressure and flow in gas extraction systems.
  • The user is able to set up comments and questions to record information at site and at each sample point.
  • Ensures consistent collection of data for better analysis.
  • Streamlined user experience reduces operational times.
