6.1 Introduction to the GFM436 Functions and Features
The GGFM436 is an ATEX accredited hand-held gas analyser designed specifically for monitoring and analysing soil
gas parameters in greenfield and brownfield (contaminated land) sites and landfill sites.
It is lightweight, small and robustly manufactured in a weather resistant case making it suitable for use even in
challenging field applications. It measures the methane, carbon dioxide, oxygen, hydrogen sulphide, hexane and
carbon monoxide content of the gas sample. It also has internal sensors for the measurement of gas pressures (or
vacuum) and flow. External sensors can be attached for the measurement of temperature and gas velocity.
