It offers understanding on OGI needs, taking into account environmental conditions as well as what OGI can accomplish. Other sections include how to use OGI as part of an LDAR process, to improve safety, plus comply with legislation.
Optical Gas Imaging is explained as "one of the most significant advances in infrared thermographic cameras over recent years."
The cameras use spectral wavelength filtering and sterling cooler cold filtering technology. This enables visualization of infrared absorption of VOC/hydrocarbon, SF6, refrigerant, carbon monoxide, or other gases whose spectral absorption matches response of the camera. OGI is now able to incorporate a 'Smart LDAR' program for safety and to visualize gas leaks.
