Ozone Monitor : medium-high range | 2.B Tech

Ozone monitor in medium-high range of 0 to 10,000 ppm allows it to be used in the analysis of off-gases in water treatment plants prior to ozone destruction.


The Model 106-MH Ozone Monitor is designed to measure ozone in the range of 0 to 10,000 ppm with a resolution of 0.1 ppm.  It can be used in the analysis of off-gases in water treatment plants prior to ozone destruction.

The Model 106-MH Ozone Monitor has many uses in industry and research, such as water treatment, food safety processes and ozone disinfection.  The application note available for download describes its use in a study on the effect of ozone treatments on the safety and quality of grape tomatoes.  The 106-MH model was used to measure the ozone concentration in the treatment chambers.  In addition, the two relays in the 106-MH were used to accurately control the ozone output of an ozone generator, ensuring that the treatments applied were well defined.

This product the 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%).
