Personal Ozone Monitor (POM)

2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the “world’s smallest ozone analyzer.” The POM is a handheld EPA-certified Federal Equivalent Method (FEM) ozone monitor that utilizes the measurement technique of UV absorption. The instrument is capable of providing highly accurate/precise ozone measurements in a package that is unique to the ambient ozone monitoring market.

0-10 ppm measurement range with 1.5 ppb precision
Handheld with battery and GPS
EPA designated as a Federal Equivalent Method (FEM) for ozone: EQOA–0815–227.

Overview

POM unit has dimensions of 4 x 3 x 1.5 inches and weighs only 0.8 lb/360 g (without battery) or 1.0 lb/450 g (with battery)
Built-in GPS so that ozone measurements may be logged continuously along with geographic location
Folded “U” shaped optical path, allowing the instrument to achieve the same path length as the Models 106-L, 202, and 205

What Happens to Ozone Inside a Ship Plume?

Products: POM

Category: Ambient Ozone Monitor

Application: Ambient Air

In this study, the 2B Tech Personal Ozone Monitor (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.
