Abstract
A test kit () includes an at least partially transparent or translucent tubular collection chamber () which has a flow control valve () at the inlet end () thereof. Flow control valve () has a mouth () that is used to engage a Schrader valve () of a HVACR system to flow pressurized refrigerant fluid into the collection chamber () via flow control valve (). The flow of the pressurized refrigerant fluid is throttled by flow control valve () to ensure that sufficient lubricating oil is separated from the refrigerant fluid and remains within the collection chamber (), even as refrigerant is expelled from collection chamber () via vent holes (). A collector () serves to accumulate separated lubricating oil. A frangible ampoule () which contains a liquid pH indicator () is crushed to contact the pH indicator with the separated lubricating oil to test the pH of the oil by color change of the pH indicator.
