Personal Ozone Monitor (POM)

The World’s Smallest Ozone Monitor

2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the Personal Ozone Monitor or “POM”. The basic POM unit has dimensions of 4 x 3 x 1.5 inches and weighs only 0.8 lb / 1.0 lb without/with battery (360 g / 450 g ). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. By folding the optical path in the shape of a “U,” it was possible to achieve the same path length in the POM as in the Models 202, 205, and 106-L and thus have similar precision and accuracy (~1.5 ppb).

The POM has been designated by the US EPA as a Federal Equivalent Method (FEM) for ozone: EQOA–0815–227.

Applications

• Personal exposure monitoring for studies of health effects of air pollutants
• Health and safety monitoring at industrial sites using ozone
• Vertical profiling using balloons, kites, RPVs, and light aircraft where space and weight are highly limited
• Long-term monitoring at remote locations where power is highly limited
• Urban arrays of ground-based detectors

Application Note

This note describes a study in which the POM was flown on a drone above Chesapeake Bay, to investigate the chemistry inside the plume of a large freighter at sea. The versatility of the POM was showcased in this work, which also made use of another POM to make complementary measurements at a ground station nearby.
