The Gas Data GFM436 handheld series of analysers is designed specifically for monitoring and analysing gas
content of landfill, biogas and contaminated land sites. It measures the methane, oxygen and carbon dioxide
content of site gases, gas pressure or vacuum, and gas velocity.
Operation is extremely simple, yet the readings obtained are
highly accurate. The instrument uses Gas Data's proprietary
infra-red methane and carbon dioxide sensors and a
combination of industry standard electrochemical gas sensor
cells. A variety of external sensors can be plugged in, e.g. vane
anemometer to measure gas velocity or a temperature probe
for ambient and other temperatures.
The GFM436 series has rechargeable Nickel Metal Hydride
batteries giving around eight hours use between charges. A
battery charger and mains unit is supplied with the instrument
and a field replaceable battery pack is also available as an
optional extra.
