2B Tech has taken the next step in miniaturization of UV-based ozone monitors by developing the Personal Ozone Monitor or "POM". The POM has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 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 (~2 ppb).

The new Model 212 Scrubberless Ozone Monitor uses the proven ultraviolet (UV) absorption method with an innovative gas-phase scrubber technology to measure ozone virtually free from interferences. In the reference mode, the instrument uses the reaction between ozone and nitric oxide (NO) to selectively remove ozone from the sample. This reaction is orders of magnitude faster than with any other ambient gas, resulting in the removal of only ozone and not potentially interfering compounds that absorb UV light. The instrument is ideally suited for measurements of ozone in heavily polluted air where interference is likely from particulates, mercury, or VOCs. The ozone monitor combines the stability of our proven dual beam ozone monitors with our selective scrubber technology to provide accurate ozone measurements in the most polluted air.
The gas-phase scrubber technology uses NO to quantitatively react with ozone and remove it from the sample. This reaction has long been used as a gas phase titration for the measurement of either NO or O3. In the Scrubberless Ozone Monitor, a low concentration of NO is added to the sample to generate ozone-free, reference air. The light intensity is measured in the reference and sample modes, and the concentration of ozone is calculated directly from Beer's Law. Nitric oxide can be supplied from an external NO cylinder and will provide over a year of gas supply. Alternatively, nitric oxide can be generated inside the instrument using an optional photolytic NO generator and an external cylinder of nitrous oxide (N2O), which is non-toxic, non-corrosive and relatively inexpensive.
All 2B Tech ambient air monitors offer remote instrument operation via RS-232, choice of averaging time (2 s to 1 hr), analog output (0-2.5 V), current output (4-20 mA), internal data logger, and optional flash memory. Our data display and graphing software allows continuous display of data which can be saved for offline analysis
