ABSTRACT:
Method and apparatus for freon and other refrigerant matching, particularly for servicing of air conditioning systems for automotive applications. The matching process is based upon the comparison of resistance or infrared absorption or other data readings of a gas-sensing resistance or infrared absorption or other transducer applied to the refrigerant fluid under test and corresponding data from reference refrigerants.
