The GFM436 is an ATEX certified gas analyser for site investigation, landfill gas control, and environmental regulation compliance monitoring.
It is a fixed configuration, measuring the proportions of CH4 (by both volume and Lower Explosive Limit), CO2, O2, H2S and CO presented in soil gas, greenfield and brownfield sites. This includes land affected by landfill operations or other industrial contamination.
Additionally, hexane content is measured to assist in areas with hydrocarbon vapours from spilt fuels, oils, or other such contaminants. This instrument has the additional capacity to measure gas pressure (differential and static) and flow rate (instantaneous and peak).
Optional extras to measure velocity and temperature are available.
