Originally developed for NASA, the OzoneWatch
is a simple, effective, and inexpensive test for ozone, a known lung
irritant. Each OzoneWatch kit contains 2 One-Hour Tests in a
vacuum-packed pouch. After one hour, the center of the test circle
will change color depending on the amount of exposure to ozone.
Simply match the color of the test card to the attached color chart
to determine ozone levels.
Useful for monitoring indoor and outdoor ozone concentrations caused
by sources such as air pollution, office equipment, UV lights,
ionizing air purifiers, etc. |
