POM^TM,袖珍式紫外臭氧分析儀

下一步的以UV為基礎的臭氧檢測儀的已經(jīng)小型化。此款POM臭氧檢測儀尺寸為4英寸×3英寸×1.5英寸，重0.75磅（340克）。由于本機有內置的GPS裝置，因此臭氧檢測值以及其地理位置數(shù)據(jù)能同時得到持續(xù)不斷地存儲。通過把它的光程折疊成“U”型，POM能有和Models 202，205，以及106-L一樣長的光程，那么它有如同這幾款臭氧檢測儀一樣的度（~2ppb）。

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).

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
