GFM 436 Portable Gas Analyser
A portable gas analyser designed for site investigation, landfill monitoring and environmental compliance monitoring
Contact Van WaltOverview
The GFM436 is a fixed configuration instrument for monitoring methane (CH4), carbon dioxide (CO2), Oxygen (O2), hydrogen sulphide (H2S) and carbon monoxide concentrations present within gas. Methane concentrations are expressed by volumetric concentrations and as concentrations at the Lower Explosive Limit (LEL). The GFM436 is a lightweight, robust and portable field instrument.
GFM436 also monitors hexane content to quantify measurement of hydrocarbon vapours from oil spills or similar. This instrument offers flow measurement (instantaneous and peak) barometric pressure and gas pressure (differential and static).
Accessories to measure gas velocity and temperature are available.
If your application requires alternative gas configurations please consider the GFM406 which can be built to your specification.
