Landtec GEM 5000 Series & SEM 5000 Portable

For Sale Landtec GEM 5000 Series & SEM 5000 Portable Landfill Gas Analyzer W/Accessories. Excellent condition with fully tested and function.

The LANDTEC GEM 5000 and SEM 5000 are complementary, intrinsically safe instruments built specifically for landfill compliance and maintenance. The GEM 5000 monitors extraction well gases (Methane, CO2, O2, plus H2S/CO on Plus models), while the SEM 5000 is a laser-based methane detector built for surface emissions surveys.
