The GFM600 Series handheld field instruments have
been developed to meet the demands of gas, flow
and velocity measurements in the biogas, landfill and
contaminated land markets.
The GFM600 instrument offers measurement of gas
velocity in gas extraction pipework using a vane
anemometer and simple LCD readout.
The GFM610 instrument offers measurement of low
gas flows and pressures from perimeter boreholes
on landfill and contaminated land sites
