The ozonator can be certified for use as a transfer standard. To determine a
calibration curve, an external ozone primary standard such as the Model
49
i Primary Standard, must be used.
Due to changes in light intensity, flow, and ambient temperature, the
calibration curve is accurate only for a short time after a transfer standard
reading is taken. Since the setting is not remembered once the instrument
is powered down, the calibration curve is not retained and must be
regenerated on instrument start up. This ensures that the calibration is
accurate. The Ozonator Manual Level screen is used when certifying the
ozone generator as a transfer standard.
