Asbestos has so many attractive properties and has often been used in a variety of forms for construction. If building materials are not properly maintained, asbestos fibers can become airborne creating significant environmental health problems. Proper sampling is key to determining airborne asbestos concentrations. Sampling methods are also available to determine asbestos concentrations in settled dust.

• Count
  Average background fiber count is less than 4 fibers per 100 fields.
  
  
• Clearing
  Filter material clears thoroughly to meet method specifications and is suitable for PCM analysis.
  
  
• Conductivity
  Cassette plastic contains over 18% carbon black for proper conductivity as tested using ASTM methods.
  
  
• Collection Area
  Inside diameter varies by only ± 5 mm2 for consistent collection area and minimized error.
  
  
• Construction
  Certified leak-free, cassette parts are manufactured with close tolerances and vacuum and pressure tested for leakage.
