Landtec GEM 5000 Plus Landfill Gas Monitor Rental $175.00 $515.00 $1,335.00

The GEM™5000 is designed specifically for use on landfills to monitor Landfill Gas (LFG) Collection & Control Systems. The GEM™5000 samples and analyzes the methane, carbon dioxide and oxygen content of landfill gas with options for additional analysis.

The GEM5000 measures flow and calculates the calorific values of the gas as well as being a useful tool for balancing the gas field. The GEM5000 gas analyzer may be used to monitor, calculate, adjust and record the flow at each monitoring point. This instrument may also be used in GA (gas analyzer) mode of operation if required. The operator may change the analyzer between a gas extraction monitor (GEM mode) or a landfill gas analyzer (GA Mode).
