Detecting Compounds that Keep Things Cool

Most refrigerants are organofluorine compounds used in air conditioning and cooling systems. Unlike the chlorofluorocarbons used in earlier systems, modern organofluorine compounds do not deplete the ozone layer. However, some blends contain VOCs and refrigerants in general can contribute to global warming. Common organofluorine refrigerants include R-134a, R407C, and R410A.

Anhydrous ammonia, or pure NH3, is a low-cost, energy efficient refrigerant with industrial applications. While NH3 is not considered a greenhouse gas, it is explosive when mixed with air and a potent irritant.

Ten tips to get the most out of your OGI Camera

Optical Gas Imaging (OGI) cameras use spectral wavelength filtering and Sterling cooler cold filtering technology to visualize the infrared absorption of VOC/hydrocarbon, SF6, refrigerants, carbon monoxide and other gases whose spectral absorption matches the response of the camera.

Optical Gas Imaging Cameras for Refrigerant Leak Detection


Handheld: FLIR GF304

Detects refrigerant gas leaks without interrupting or shutting down operations in food production, storage and retail; pharmaceutical; automotive; and air conditioning.


Handheld: FLIR GF306

Visualizes refrigerants such as Anhydrous Ammonia and Dichlorodifluoromethane (FREON-12). This portable, non-contact system allows you to quickly scan wide areas for leaks, so you can begin repairs sooner.
