GASTEC Color Dosimeter Tubes provide reliable, on-the-spot Time-Weighted
Average (TWA) monitoring of worker exposure to gases and vapors. Simple-to-use
and easy-to-read, snap off the pre-scored end of the tube and insert it into
a tube holder. Place the tube on a worker near the breathing zone, except
when measuring carbon dioxide (see second Tech Tip below). No pump, chart,
or analysis is needed. Read the printed calibrated scale on the tube for
exposure measurement in parts-per-million-hours (ppm-hours). Divide the reading
by hours sampled for ppm levels.
- Easy-to-use
On-the-spot readings with no interpretation, long calculations,
charts, or pumps
- Sampling flexibility
Perform STEL, TWA, or long-term sampling up to 24 hours
- Economical
