The Zefon Inhalable Dust sampler is a reusable filter cassette with a sampling head designed to measure the worker's exposure to inhalable particulates and respirable dust. When sampling at the recommended flow rate of 2 LPM, it collects a particle size distribution that includes particles of 100 micron and smaller. This meets the definition set forth by ACGIH for inhalable particulate.
The sampler is comprised of two main parts. The main sampling head, and a removable filter cassette assembly. This allows easy transport of the filter cassettes for analysis while the sampling head can then be reloaded with a new cassette and sampling may continue.
The physical design of the Zefon Inhalable Dust Sampler is a replica of the sampling head developed by the Institute of Occupational Medicine (IOM) in Scotland during the 1980’s and which is currently marketed under license from the IOM by SKC. As a result the Zefon Inhalable Dust Sampler features identical performance and part interchangeability with the samplers marketed by SKC.
- 50% cut point at 100 microns when used at 2 LPM
- Conductive plastic cassette design
- Small (128 x 33 x 25 mm) including lapel clip
- Light Weight (<1 ounce or about 25 grams)
- Sampling Head and Cassette parts are interchangeable with
the SKC IOM Sampling Head and cassette.
- Complies with or meets the requirements of the following standards:
-ACGIH definition of inhalable particulate matter
-NIOSH Method 5700 for particulate formaldehyde
-NIOSH Method 5525 for Isocyanates (stainless steel cassette only)
-British Method MDHS 14/3 for inhalable dust in air
-British Method MDHS 25/3 for organic isocyanates in air
-British Method MDHS 6/3 for lead in air
Each Zefon Inhalable Dust Sampler comes with the sampling head, 1 cassette assembly and a cassette transport clip.
