C3101 Particle Screens $20.00


Item C3101 is a 10-pack of particle screens.

These screens were designed for use in particle board manufacturing and mines.  Particles containing your chemical of interest (usually formaldehyde, styrene, or mercury) can fall through the openings in the badge, causing your results to be biased high.  These screens prevent particles from entering the badge.

Note: all mercury badges are sold with the screen already included.  Please be sure to remove the screen after use.

IMPORTANT: indicate on the LRF/COC that a particle screen was used.  Use of a screen raises the reporting limit of the badge because the sampling rate is slowed by the screen.  Look for a note on the report that indicates a screen was used during sampling.  For instance, the chemical name will appear as “FORMALDEHYDE (PART. SCREEN)”.  Contact us if you used a screen and do not see a note from the lab.

This badge collects the following:

Formaldehyde (using the 571 badge)

Styrene (using the 566 badge)
