1.2 Options
The following options are available for the AX 300-I analyzer:
 A-Option—2½-digit LCD instead of 3½-digit
Note: Contact the factory for modifying your analyzer for 2½-digit LCD. For
RS-232 reconfiguration, see Section 2.1.5.
 B-Option—RS 232 digital output instead of 0-1VDC
 Universal Pole Mounting Clamp (P/N CP 2345)
 V-Mount Pole Clamp (P/N CP 2344)
 V-Mount Wall Adapter P/N B 647)
 0-1 VDC Interface Cable (P/NB-75554)
 RS 232 Interface Cable (P/N B-75555)
1.3 Applications
The AX300-I analyzer is intended for spot checking the concentra-
tion of oxygen in gas mixtures used in applications such as Anesthesia
gas delivery and Respiratory care, and is intended for adult, pediatric
and neonatal populations.
1.4 Operation Summary
The AX300-I analyzer uses Teledyne Analytical Instruments’ Pa-
tented R17MED oxygen sensor. The sensor output is used to determine
the oxygen gas concentration that is displayed on the LCD screen. The
concentration alarm of AX300-I analyzer is non-defeatable and will
alarm when the oxygen concentration falls below the threshold of 18%.
This alarm is tied to sensor fail/disconnect alarm that will also warn the
user of a possible sensor problem when the oxygen concentration is less
than 18%. When a fault is detected, the
SENSOR indicator is displayed
on the LCD, and the audible and visual alarms are activated.
The Class R17MED oxygen sensor is a disposable sensor. The sen-
sor has a cathode (sensing electrode), an anode (counter electrode), and
a compatible electrolyte, and is packaged in a small plastic sensor body.
Oxygen entering the sensor reacts with the anode and a proportional cur-
rent is collected at the cathode, which is then converted into a digital
signal and displayed on the LCD screen on the analyzer.
Used with the R17MED sensor is a removable plastic diverter. This
diverter is used to facilitate the transport of gas mixtures through the
sensor. The diverter, packaged separately when shipped, is necessary
when the tee adapter is used to sample gas flowing through a tube.
