Ozone Analyzer 106-L

The Model 106 series of ozone monitors was designed specifically for the industrial ozone industry to cover four different ozone concentration ranges by varying the optical path length.  The ranges are: -L (low, 0-100 ppm); -M (medium, 0-1,000 ppm); -MH (medium high, 0-10,000 ppm, 0-1 vol%) and -H (0-20 wt%, 0-14 vol%).  The Model 106 series is designed as an “ozone monitor on a board” in which nearly all of the components are mounted directly to the printed circuit board with very few wire connections, making these instruments highly robust and very easy to service.  As seen in the images above, all models are available in a standard enclosure, Industrial enclosure, or with no enclosure for OEM applications for those who want to mount the instrument in their own enclosure or use it as a component of a larger system. For more details on OEM applications see: Model OEM-106.  Configurations for multi-channel sampling are available for Models 106-L, 106-M, and 106-MH.

The Model 106-L Ozone Monitor is designed for measurements of ambient ozone concentrations down to very low ppb levels. However, because of the large dynamic range of our ozone monitors, the Model 106-L also can be used for accurate measurements of ozone at concentrations up to 100 ppm (100,000 ppb).  The accuracy and precision of this instrument is comparable to our our original Model 202 Ozone Monitor widely used for field measurements by atmospheric researchers`

The Model 106-L Ozone Monitor is recommended for workplace health and safety monitoring where ozone is being produced and used in a wide range of industrial applications such as water treatment, food processing, aquaculture, fruit and vegetable warehouses, and others.
