Tanabyte - Model 723 -Transfer Standard Photometric Ozone Analyzers with Cal/Sample Valves
In addition to the Equivalent Method UV Photometer, the Model 723 includes an internal zero air supply, ozone generator and a valve to switch the photometer inlet from sample air to the ozone generator output. The 723 can be used as an ambient analyzer with internal zero/span or as an Ozone Transfer Standard Calibrator, for calibrating external analyzers. A three port ozone output manifold allows ozone to be directed to the internal photometer and an external instrument simultaneously. The internal zero air supply provides clean pollutant-free air to the ozone generator with sufficient flow to supply ozone to two photometers.
