A compressor includes a casing accommodating a refrigerant passageway, a compression mechanism and a pipe. The compression mechanism is disposed in the interior of the casing to discharge compressed refrigerant into the refrigerant passageway. The pipe extends from inside of the casing to outside of the casing. The pipe includes two ends. One is a closed end disposed in a predetermined position inside the refrigerant passageway. The other end of the pipe is an opened end disposed outside the casing. The pipe is preferably sized so that a measuring instrument can be inserted into the pipe through the opened end.
