ABSTRACT:
A test kit and method for determining in a semiquantitative manner the amount of oil mist in a compressed-air stream, which method comprises bleeding a small sample from the compressed-air stream containing oil mist whose concentration is to be determined; directly impinging the compressed-air stream so bled for a defined time period through a defined orifice onto the surface of a coated plate containing an ultraviolet radiation indicator to capture the oil-mist particles in the compressed-air stream, thereafter comparing the test plate with a standard plate of known concentration of oil mist under ultraviolet radiation to determine the degree of flourescent quenching as an indication of the amount of oil mist in the compressed-air stream.
