Landtec GEM 2000 Landfill Gas Monitor Rental $165.00 $495.00 $1,275.00

The GEM 2000 was designed by CES-LANDTEC specifically for use on landfills to monitor landfill gas (LFG) extraction systems, flares, and migration control systems. The GEM 2000 combines the GEM 500 and the GA-90 into one faster, more accurate, intrinsically safe instrument.

The GEM 2000 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. The GEM 2000 calculates and displays gas flow rate.

It also measure and displays Btu content, temperature (w/optional probe), relative and atmospheric pressures and CH4 LEL (Lower Explosive Limit).
