Assay Technology’s, 581 Aldehydes badge is our fastest sampling rate, lowest reporting limit aldehyde badge. This monitor was designed to get a reporting limit as low as possible.

The 581 monitor will work for formaldehyde and the reporting limit will be lower than the existing 571 badge. However, the 571 badge is still the badge Assay Technology recommends for formaldehyde monitoring.  In most cases, it easily meets reporting limit requirements for OSHA, even the OSHA STEL, unlike other badges on the market.

In October of 2017, the TraceAir badge was updated to address a common complaint end users have had since it was introduced by DuPont many years ago.  The badge was too easy to pull apart when removing the sampler caps.  The TraceAir configuration gets an update.
