35% Carbon Dioxide (CO2), 50% Methane (CH4) Calibration Gas

Our landfill gas meter calibration gas consists of 50% methane (CH4) and 35% carbon dioxide (CO2).  The calibration gas is typically used for calibrating landfill gas meters such as the Landtec GEM 2000 and GEM 5000.  The calibration gas is NIST traceable and comes with a certificate.
