Model 106-H Ozone Monitor

The Model 106-H is a high concentration ozone analyzer designed to control the output of an ozone generator. This instrument is designed to be installed in-line with an ozone generator and ozone process.

  • Measurement range of 0-20 wt% with 0.01 wt% precision
  • Designed to measure the ozone output of generators that use either air or oxygen as feed gas
  • Flow-through configuration with no air pump; designed to sample at either high pressure (up to 50 psig) or partial vacuum

Overview

The Model 106-H is a flow-through ozone analyzer designed to measure high concentrations of ozone and provide feedback control of ozone generators. This instrument is meant to sample from a pressurized source (up to 50 psig) and can handle flow rates ranging from 0.5 – 55 L/min. Our Model 106-H is known for being a low-power (3 watt) highly portable analyzer that is available in three different configurations.

 

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)

Case Studies

Researchers at the University of São Paulo are studying the use of ozone as a more environmentally sound method for modifying the properties of starch. Industrial sectors that use starch include food, petrochemical, adhesives, paints, and others. This study applied high ozone and used the Model 106-H Ozone Monitor to follow the inlet and outlet concentrations of a reactor containing the starch. The study identified several techniques for optimizing starch properties.
