ABSTRACT:
A method and apparatus for testing for the presence and concentration of contaminants in a refrigerant. A sample of the refrigerant is withdrawn from a closed refrigeration, air conditioning or similar system and passed through a testing tube. Various sections of the tube contain provisions for the removal of oil entrained in the sample, for the removal of water contamination from the sample and for providing visual indications of the presence and concentration of a plurality of contaminants that may be present in the refrigerant.
