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.
