Hydrocarbon capacity added to handheld gas analyser

Gas Data’s new GFM436 handheld gas analyser will help provide a more complete picture during environmental monitoring with the ability to measure six different gases, including CH4, CO2, O2, H2S and hexane. According to Gas Data, the new analyser provides a step change in site investigation and landfill gas analysis.

The addition of hexane to the spectrum allows the presence of other hydrocarbons to be measured, widening the scope of the monitor for use during site investigations of greenfield sites, brownfield sites and land affected by landfill operations or other industrial contamination.

“Through our long-term relationships with our clients we were able to collect really valuable feedback for our product development process for the GFM436,” says Gas Data managing director Matthew Humphreys.

“Clients still wanted the accuracy and reliability of our gas sensors, but they also asked for enhanced usability.”

“The GFM436 incorporates enhancements such as a bright LED display, intuitive operator buttons and a new PC-based software management application. It makes it easy to use the device on a day-today basis.”

The GFM436 measures the lower explosive limit (LEL) and also determines a photo ionisation detector (PID) compensation factor for use with other PID equipment. Gas pressures can be measured as differential or static and the flow rate can be measured at the instantaneous or peak levels.

A temperature sensor can be plugged in for gas temperature measurements, or a vane anemometer to measure the velocity in a gas extraction system pipeline.
