Which diffusive monitor should I use?
Assay Technology offers more diffusive monitors for more chemicals than any other manufacturer! This is great news for those who want easy, accurate methods for personal monitoring. Check out our simple guide below to find the right monitor for your needs.

ORGANIC VAPOR MONITORS
Assay Technology provides three different Organic Vapor monitors that can sample for over 100 Organic Vapors. Why three?
Think of it like three pumps with three different flow rates, but they won’t break nor will they have to be calibrated.
The slow flow pump is good for long sampling times at high concentrations. The chemicals are likely to be those with high PELs, like Acetone and Ethanol. See the 546 badge.
The fast flow pump is best for short sampling times or very low concentrations, like measuring Indoor Air Quality and chemicals with low PELs, like Benzene. See the 525.
The medium flow pump is for everything else. See the most versatile, most popular 566.
Our most popular, versatile monitor. Use for most sampling situations.
|525 TraceAir® II:
Our fastest sampler for short term or IAQ sampling. If concentration is low enough, the 525 is OK for TWA or longer monitoring.
Our sampler with the highest capacity. Best used when monitoring for more than 4 hours for chemicals with PELs greater than 200 ppm. If reporting limit is OK, 546 will work for all chemicals that work on the 566 or 525.
|While all three can work for almost every chemical, choosing which one will work best for you depends on the

Should/can I use a badge?
Our badges work for hundreds of chemicals for STEL, PEL, and IAQ monitoring; however, badges are not for every chemical or every situation. See our page on the advantages/disadvantages of diffusive monitors for more information.
