The 581 is our fastest sampling rate aldehyde. Our traditional aldehyde collecting media used in our 571 badge was inserted into the TraceAir® II configuration. This monitor was designed for the ACGIH Ceiling limit of 0.05 ppm for Glutaraldehyde.

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. 

However, customers that are going to use the NIOSH REL to evaluate their formaldehyde results should use the 581 badge, not the 571.  The NIOSH REL is 0.016 ppm, which is over 40 times below the OSHA PEL of 0.75 ppm.  So the fast sampling 581 with an 8 hour reporting limit of 0.0014 ppm is preferred.

*** 581 REPLACES 580 ***

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.
