    • Meets ACGIH and MDHS 14/3 requirements for inhalable particulate
    • 50% cut point at 100 microns when used at 2 LPM
    • Small (128 x 33 x 25 mm) including lapel clip
    • Light weight (< 1 ounce or about 25 grams)
    When operated at 2 LPM the Inhalable Dust sampling head collects a dust sample that follows the particle size distribution as described by the ACGIH for inhalable particulate. The ACGIH descriptions applied to particle size selective TLVs are presented below.

    Respirable Particulate Matter: Those materials that are hazardous when deposited in the gas exchange region (50% cut point at 4 microns).

    Thoracic Particulate Matter: Those materials that are hazardous when deposited anywhere within the lung airways and in the gas exchange region (50% cut point at 10 microns).

    Inhalable Particulate Matter: Those materials that are hazardous when deposited anywhere in the respiratory tract (50% cut point at 100 microns).


    The inhalable fraction size distribution is described by the following table. For particles of 1 micron diameter, nearly all (97%) are captured by the sampler and collected onto the filter. For particles of 100 microns in diameter, 50% are collected onto the filter. This approximates the size distribution in the respiratory tract.
