Inspectahire carries out optical gas imaging (OGI) services for gas leak detection applications, including SF6 surveys for sulphur hexafluoride.

Optical gas imaging using thermal cameras offers a number of benefits compared to traditional "sniffers" because they scan a broader area much more rapidly and in areas that are difficult to reach with contact measurement tools. Gas leaks are displayed from a safe distance as a plume of vapour in the infrared image and, once a leak is found, a TVA can be used to quantify the concentration.
