POM便携式紫外臭氧检测仪:

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
