Model 306 Installation Guidelines
Typical Installation: Connection to a Device Drawing Flow from the Model 306
The Model 306 is frequently used to calibrate an ozone monitor or to provide a known ozone
concentration to another kind of equipment that draws flow from the calibrator. The Model 306 is
designed for this type of installation. Inside the Model 306, an air pump maintains a total flow of ~
3 L/min through the ozone generator. Any portion of the total flow that is not being drawn into the
user’s equipment is vented through an internal ozone scrubber and vented inside the enclosure
(Figure 1).

and vent for any unused portion of the total flow rate.
