Model 734 Ozone Primary Standard Calibrator

734 module

The Model 734 includes an Ozone Photometer configured as a Primary Standard. A Primary Standard uses external zero air in place of an ozone scrubber for the reference measurement.

In addition, the 734 includes a built-in ozone generator that provides a very repeatable ozone output at concentrations ranging from only a few PPB to greater than 1 PPM at a flow rate of up to 5 LPM. The photometer's ozone measurement can optionally be used to precisely regulate the output of the ozone generator to a specified concentration.
