Gas Imaging Cameras -Making Invisible Gas Leaks Visible

Many chemical compounds and gases are invisible to the naked eye. Yet many companies work intensively with these substances before, during and after their production processes. This article discusses how thermal imaging cameras can be adapted to visualise fugitive gas leaks. The GF-Series thermal imaging cameras from FLIR Systems (see figure 1) were developed to produce a full picture of the scanned area and visualise gas leaks as ‘smoke like images’ on the camera’s viewfinder or on an inbuilt LCD, thereby allowing the user to see fugitive gas emissions. The GF-Series imaging technology allows gas leaks to be viewed in real time and images recorded in the camera for easy archiving.
