For industrial ozone applications, 2B Technologies offers the Model 106-L, 106-M, 106-MH and 106-H Ozone Monitors, where L, M, MH and H refer to Low (0-100 ppm), Medium (0-1,000 ppm)06-, Medium-High (0-10,000 ppm) and High (0-20 wt%) ozone concentrations, respectively. These instruments have different optical path lengths in order to accommodate an extremely wide range of ozone concentrations, spanning more than eight orders of magnitude.
