Analytical Industries Palm O2 D Oxygen Analyzer - Manual (Page 3)

In order to obtain optimum performance, the operation of the device must be
performed in accordance with these Instructions for Use. Maintenance should
be performed only by trained personnel authorized by the manufacturer.
1.2 Intended Use
The Palm O2 Oxygen Analyzer is intended to measure and display the concen-
tration of oxygen of oxygen in compressed breathing air tanks intended for
scuba diving.
1.3 Device Description
The Palm O2 Oxygen Analyzer is designed to be handheld but can be tempo-
rarily placed in a fixed position on a pole or shelf with optional bracket attach-
ments as illustrated in Section 8.1. A remote sensor option is available which
makes the Palm O2 more flexible and easier to use. Either way, it provides
continuous, fast, reliable and accurate oxygen measurements.
The device utilizes an electrochemical galvanic fuel cell type oxygen sensor of
the type that is extensively used to measure oxygen concentrations from 0%
to 100% in gas streams. Oxygen, the fuel for this electrochemical transducer,
diffusing into the sensor through a gas permeable membrane reacts chemi-
cally at the sensing electrode to produce an electrical current output propor-
tional to the oxygen concentration in the gas phase. The sensor has an abso-
lute zero meaning that when no oxygen is present to be chemically reacted
the LCD displays 00.0 oxygen.
The sensor’s signal output is linear over the entire range, remains virtually
constant over the specified useful life and drops off sharply at the end. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful life like a battery. Inasmuch as the sensor is a transducer in its own
right, its expected life is not affected by whether the analyzer is ON or OFF.
A battery powered state-of-the-art micro-processor converts the sensor’s sig-
nal output representing the partial pressure of oxygen in the gas stream being
analyzed. The resulting oxygen reading is displayed by a large easy to read
backlit liquid crystal display (LCD) that has a resolution of 0.1% oxygen. The
microprocessor is controlled from a keypad and provides system diagnostics
and warning indicators for continuous monitoring that enhance both safety
and effectiveness.
Prior to shipment, every device is thoroughly tested at the factory and docu-
mented in the form of a Quality Control Certification that is included in the
Instructions for Use supplied with every device.
