The Gas Data GFM430 can be used for measuring the individual components of biogas (CH4, CO2, H2S and O2) concentration, as well as temperature. A dedicated biogas analyser, the GFM416 is available to hire or buy.
Ground-gas/landfill monitors are available in both portable and in-borehole versions. For 'spot' surveys there is the portable Gas Data GFM430/5/6 and for long-term 'in situ' borehole monitoring there is the Ion Science Gasclam.
The GFM436 portable landfill gas monitor is hand-held and lightweight. Also, monitoring of several boreholes is possible during one site visit.
The Gasclam measures gas (CH4, CO2, VOCs, H2S, CO, O2), concentrations, temperature and borehole and atmospheric pressures.
Measurements can be taken at user-defined intervals. The default setting for the GasClam is to sample every hour and upload data every six hours providing up to two months battery life (with rechargeable D-cell batteries).
After the GasClam has been physically installed in the ground it can start collecting data in less than 2 minutes. The GasClam will continuously collect data at intervals set by the user.
The GFM 436 Landfill Monitor measures six gases: methane, carbon dioxide, oxygen, carbon monoxide, hexane.
We advise that instruments are returned every 12 months so that they can be serviced/ maintained for optimum operational use.
The GFM430/5/6 measures gas (CH4, CO2, H2S, CO), concentrations, temperature and borehole, atmospheric pressures plus borehole flow.
