Assay Technology’s 546 High Capacity Organic Vapor Badge is excellent for all day monitoring of Organic Vapors that have high PELs (greater than 200 ppm).  The 19 hole sampling face greatly reduces the possibility that the collection media becomes saturated, making a second wafer inside the badge unnecessary in most environments.  The 8 hour reporting limits are different for each chemical, but they are about 0.5 ppm, which is well below most PELs.  Check our sampling guide for the chemical you are interested in.  The 546 badge is not usually recommended for STEL (15 minute) monitoring.  See our 566 or 521 badge.

Assay Technology also manufactures two other Organic Vapor Monitors, 566 and 521. For assistance in choosing which is best for your situation, use our Guide.

Please Note:  The 566 monitor can NOT be used for acetic acid monitoring.  See our Acetic Acid Monitor: 543.

Industrial Hygiene Labs:

  • Sampling Rates are in our Sampling Guide and Requested Sampling Rates or search by CAS #.  Contact us if you can not find a rate you need.
  • Opening the ChemDisk is made much easier using the pick we specify.
  • Media is available for QC testing.  Use our M products  (M566).
  • The media inside the 546 badge is the same media that is in the 566 badge.  The only difference is the sampling grid.

Why Prepay for the Analysis

Customers can purchase samplers with the analysis at AT Labs’ AIHA-LAP, LLC accreditated laboratories already pre-paid.  Since both the monitor and analysis is sold at the same time, the price is significantly lower than buying them separately. The -1 products come with the analysis of one chemical prepaid. The -4 products come with the analysis of up to 4 chemicals. This  satisfies most needs.

However, at times, a customer will need more chemicals than they have prepaid for. When this happens, a customer can simply request the additional chemical and will be billed for it after the report is completed.
