Fast Methane Analyzer
Brand: Los Gatos Research, IncLGR’s Fast Methane Analyzer (FMA) provides extremely precise measurements of methane (CH₄) and water vapor at up to 20 Hz. In addition to accurately monitoring typical ambient methane levels, the unprecedented response of LGR’s FMA allows measurements at high mole fractions (to 1,000 ppm with extended range option) for applications including landfills, peatlands and chamber studies.
