The CES Landtec GEM-500 provides automatic sampling and analysis of gas composition (% by volume) CH4 (100% & LEL), CO2, O2, balance gas, temperature and pressures. Also calculates gas flow rates as well as Btu content. The GEM 500 was specifically designed by CES-LANDTEC for use on landfills to monitor landfill gas (LFG) migration control systems, gas extraction systems, flares, migration probes, LEL levels, subsurface fires, and more.
The GEM 500 automatically samples and analyzes the methane, carbon dioxide and oxygen content of landfill gas. The easy to read LCD screen shows the results as percentages of CH4, CO2, O2 and “balance” gas (typically nitrogen). The GEM™500 also calculates and displays gas flow rate. Btu content, temperature, pressures and LEL (Lower Explosive Limit).
