Model 106-M Ozone Monitor

The Model 106-M is a versatile medium-range (0-1,000 ppm) ozone analyzer designed for industrial applications ranging from off-gas measurements in water treatment plants to the use of ozone to prevent ripening of fruits and vegetables. Our Model 106-M uses the UV-absorption measurement technique to produce highly accurate measurements (± 2%).

  • Available in a Standard (Benchtop Enclosure), Industrial/NEMA Enclosure, or as an OEM
  • Widely used in applications involving ozone disinfection/sterilization of hospital rooms, cruise ship cabins, and workspaces
  • Optional corrosion-resistant modification for use with ozone generators where feed gas is air instead of oxygen

Overview

The Model 106-M Ozone Monitor is designed for measurements of ozone in the range 0-1,000 ppm with a resolution of 0.01 ppm. This highly accurate ozone monitor has been widely used around the globe since 2006 by industrial customers looking to measure medium-range concentrations of ozone.

 

About the 106 Series:

  • Designed for industrial ozone applications to cover four different ozone concentration ranges by varying the optical path length.
  • Highly robust and easy to service; all components are mounted directly to the printed circuit board with few wire connection
  • Available in the three following configurations: Standard Enclosure, Industrial Enclosure, or with no enclosure (OEM version)
  • Industrial/NEMA Enclosure is available with single channel, three channel, or six channel sampling manifolds (106-H only available as single channel)
