The 566 Organic Vapor monitor is our most versatile and popular organic vapor badge.  The 566 utilizes the popular ChemDisk II configuration and a flexible, inert charcoal wafer.  Smaller and much easier to use than other badges on the market.  The  76 hole sampling grid allows for sampling rates about 8 mL/min.  The 8 hour reporting limits vary from chemical to chemical (See our Sampling Guide), but most are in the 0.1 ppm range, well below most OSHA PELs and NIOSH RELs.  In addition, the badge also has much more sampling capacity than other badge and tube methods.

Assay Technology also has two other Organic Vapor badges for more extreme environments.  The 546 High Capacity Monitor is used when monitoring an environment for chemicals with high PELs (200 ppm and higher).  The 525 Trace Air Organic Vapor Monitor is used for STEL and IAQ monitoring where low reporting limits are essential and low concentrations are expected.  For assistance in choosing which is best for your situation, use our Guide for selecting which Organic Vapor badge you should use..

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

Use For

The extremely versatile 566 badge can be used in most environments.

  • STEL and Ceiling
  • TWA
  • IAQ
  • Can be used for longer periods of time

If very low reporting limits are needed and there is believed to be very little organic chemicals in the air, such as an Indoor Air Quality situation, then the fast sampling  521 TraceAir badge may be the best badge.  If concentrations of 200 ppm and higher are expected during an 8 hour monitoring, the High Capacity 546 badge may be best.  Call our customer service department for advice or review our Guide online.

Why Prepay for the Analysis?

Saves you Time and Money

Customers can purchase samplers with the analysis at AT Labs’ AIHA-LAP, LLC accredited 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. These two choices satisfy most customers’ needs.

At times, customers will need more chemicals than they have prepaid. When this happens, they can simply request the additional chemical and will be billed for it after the report is completed.  The price will vary depending on the type of analysis.  The easiest way to determine how much more is to give us a call.  However, to determine the price yourself,  go to Sampling Guide, search for your chemical.  Then expand the information for that chemical and you will “Price Code Compatible Chemical” column(E.g. A705-X, A707-X).  Go to the Price List to determine the price per extra chemical.

Trick of the Trade:

If you need to monitor for 2 chemicals, buy the 566-1AT badge and ask for an additional chemical.  If you need to monitor for more than 2 chemicals, buy the 566-4AT
