Introduction
The Teledyne Analytical Instruments AD300 Oxygen Analyzer
here after referred to as AD300 and MD300 Oxygen Monitors with
alarms here after referred to as MD300 are portable instruments that
provide fast and accurate oxygen monitoring. In addition, the model
MD300 incorporates an audio/visual alarm capability. These instruments
are designed to monitor up to 100% oxygen concentration in breathable
gas mixtures. Because they are microprocessor-based, the AD/MD300
series have a unique combination of features that make them very easy
to use. The operator interface is accomplished through a series of
buttons located conveniently on the front face of the instrument. The
MD300 front face interface is shown in Figure 1-1. The AD300 is
similar but without the battery and alarm test buttons is shown in Figure
1-2.
