Gas Data GFM436 ATEX Site Investigation, Landfill and Compliance Gas Analyser

The GFM 436 is an ATEX accredited instrument for site investigation, landfill gas control, and environmental regulation compliance monitoring. It is a fixed configuration, measuring the proportions of methane (by both volume and Lower Explosive Limit), carbon dioxide, oxygen, hydrogen sulphide and carbon monoxide in soil gas present in greenfield and brownfield sites, as well as land affected by landfill operations or other industrial contamination.

Additionally, hexane content can be measured to assist in areas with hydrocarbon vapours from spilt fuels, oils or other contaminants. This instrument has the additional capacity to measure gas pressure (differential and static) and flow rate (instantaneous and peak).

An optional temperature sensor can be plugged in for gas temperature measurements or, alternatively, a vane anemometer can be attached to measure the velocity in a gas extraction system pipeline.
