The GEM-500 was specifically designed by Landfill Control Technologies (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 and "balance" gas (typically nitrogen).
The GEM-500 also calculates and displays gas flow rate, Btu content, temperature,
pressures and LEL (Lower Explosive Limit). The GEM-500 is an all-weather, self-contained
portable monitor which uses a self-compensating infrared gas analyzer, rechargeable
power supply for all day use, an internal sample pump capable of drawing a gas sample
at up to 70" vacuum.
Automatically displays and records Methane, Carbon Dioxide and Oxygen concentrations,
as well as gas flow rate, Btu content, temperature, pressures and LEL
