Model 106-MH Ozone Monitor™
Recommended for Industrial Ozone Applications for Concentrations in the Range 0-10,000 ppm
Standard Enclosure Industrial Enclosure OEM Version
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, an 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 (3-channel and 6-channel configurations).
The Model 106-MH Ozone Monitor is designed for measurements of ozone in the range 0-10,000 ppm with a resolution of 0.1 ppm. A common application is off-gas analysis in water treatment plants before ozone destruction.

Application Notes
The Model 106-MH Ozone Monitor has many uses in industry and research, such as water treatment, food safety processes, and ozone disinfection. This Application Note describes its use in a study of the effect of ozone treatments on the safety and quality of grape tomatoes. The Model 106-MH enabled the measurement of the ozone concentration in the treatment chambers. In addition, the two relays of the Model 106-MH were used to precisely control the ozone output of an ozone generator, ensuring that the applied treatments were well defined. Linked below is a short write-up summarizing the paper published on this study.
