Ozone Monitor [106]

For industrial ozone applications, 2B Tech 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. Additionally, the Model 106-H was designed with a flow through path that can be pressurized to up to 50 psi for in-line measurements with ozone generators. All three models are available in either a standard enclosure or NEMA enclosure.  Configurations for multi-channel sampling are available for Models 106-L, 106-M, and 106-MH.
The Model 106 series was designed as an "ozone monitor on a board" in which nearly all of the components are mounted directly to the printed circuit board. Thus, the Model 106 may be purchased without the enclosure for OEM applications. See: Model OEM-106.
The Model 106-L is designed for ambient low measurements down to very low ppb levels and has been designated by the EPA as a Federal Equivalent Method (FEM) for monitoring for compliance with the US Clean Air Act:  EQOA–0914–218.
