	Two Industry-Standard Monitors in One GEM™2000, the newest handheld landfill gas monitoring instrument from LANDTEC, is designed for analyzing LFG composition and calculating flow. The GEM™2000 combines the capabilities of the now discontinued GA-90 for monitoring gas migration probes and the GEM-500 for monitoring gas extraction systems. The GEM™2000 in certified Intrinsically Safe and offers improved speed and accuracy. Download manual (PDF)
	Smart, Portable Surface Gas Detection SEM-500 is a compact, microprocessor based instrument used to monitor the air above the surface of the landfill for methane emissions. The SEM-500 is a Flame Ionization Detector (FID) that includes the DataField SEM module software and an enhanced wand. The enhanced wand features a display screen that allows the field technician to carry the instrument in a backpack carrier and operate the instrument conveniently.
