Introduction
he GFM400 hand – held 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 reading
obtained are highly accurate. The instrument
uses 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 GFM400 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.
