  • System and method for identifying automotive and commercial refrigerants
    Patent number: 5610398
    Abstract: A system and method for determining the presence of multiple vapor gases in a refrigerant sample. An infrared light source illuminates a refrigerant sample located in a test area between the light source and a plurality of infrared detectors. Each of the infrared detectors is sensitive to a different predetermined wavelength range of infrared light, with each of the detectors outputting a separate electrical signal corresponding to the infrared light received in its respective wavelength range. A processor then reads the output electrical signals and determines whether the electrical output signals correspond to a particular refrigerant and displays the result of the determination on a display.
