1.2 Intended Use

The AII-3000 Series Oxyge n Analyzers are intended to meas ure and display
the concentration of ox ygen in compressed bre athing air tanks intended for
scuba divi ng, for perso nnel saf ety, ar ea moni toring , O2 defi cienc y in conf ined
spaces, checking breathing air tanks and confirming the O2 levels prior to
welding.

1.3 Device Description

The AII-3000 S eries Oxygen Analyzers can be positioned on a table top or
pole (tri po d wi r e sta nd and V-m o u nt dovetai l attachments ar e m ounted o n t h e
back of the device) and are readily portable from one location to another.
They pro vi de con ti nuous , f ast, rel iabl e a nd ac cur at e oxyg en me asur eme nts of
up to respiratory care systems.

The devices utilize an electrochemical galvanic fuel cell type oxygen sensor of
the type t hat is exte nsivel y used to meas ure o xygen co nce ntratio ns f rom 0%
to 100% in gas streams. O xygen, the fuel f or this electroch emical tr ansducer,
diffus ing into th e sensor thr ough a g as permeabl e membra ne reacts ch emi­cally at the sensi ng electro de to produ ce an elect rical curr ent o utput propo r­tional to the ox yg en con ce ntra tio n in the g as p has e. T he s enso r h as an abso­lute 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 t he specif ied us eful li fe and dro ps off sharply at the e nd. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful l ife like a ba ttery. In asmuch as t he sensor i s a transdu cer in its own
right, its expected life is not affected by whether the analyzer is ON or OFF.

A batter y pow ered st ate-of -the-ar t mi cro-pro cesso r con verts t he s ensor’ s sig­nal output repr esentin g the partial pr es s ure of ox ygen in t he gas s tream b ei n g
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 features like system
diagnostics, warning indicators, controls and an alarm capability for continu­ous monitoring that enhance both safety and effectiveness.

Prior to shipment, every device is thoroughly tested at the factory and docu­mented in the form of a Quality Control Certification that is included in the
Instructions for Use su pplied with ever y device.

5 Operation

5.1 Principle of Operati on

The AII-3000 Series Oxygen A nalyzers utilize 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
electro chemical tra nsduc er, di ffus ing i nto t he s ensor t hrou gh a gas p ermeabl e
membra ne react s chemi cally a t the s ensing electrod e to produce an elec trical
current output pr oportio nal to the ox ygen concentration in t he gas phase. T he
sensor has an absolute zero meaning that when no oxygen is present to be
chemically reacted th e LCD displays 00 .0 oxygen.

The sens o r’ s s i gnal o utput i s l i near over the e nti r e r a nge, r em ai ns vi rt ual l y con­stant over th e specified us ef ul li fe and drops of f s harpl y at the end. Th e sensor
itself re quires no mainte nance and is simply r eplaced 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.

The relationship between the sensor’s signal and changes with the oxygen
concentration is both proportional and linear, thus allowing single point calibra­tion. Ot her factor s t hat can af f ect the si gn al o utput are descr i be d i n Secti on 5 .2

5.2 Application Consideratio ns

Effect of Temperature

All mem bra ne clad electro ch emi cal se nsor s are t em perat ur e depe ndent d ue t o
the expa ns i o n and contr action o f the Teflon sens i ng mem br a ne. A s result m o re
or less of the sample gas including oxygen to be reacted diffuses into the sen­sor. The oxygen s ensor’s electrical current signal output varies linearly with
oxygen concen tr ati o n . T he s i gnal als o varies with changes in am bi en t tem pera­ture. The temperature coefficient is typically 2.54% of the signal or reading per
degree C change in temperature.

The tem peratur e depe ndent cur rent si gnal ou tput is compens ated by us ing a
resistor-thermistor network. With a proper resistor-thermistor network, the
signal can b e compens ated to w ithin +

5% of the oxygen reading over the 5­45°C tem p er a t ure range. Thi s i s the wors e case s i tuat i on when goin g f r o m o n e
extreme of the operating temperature range to the other. The error will be
elimi nated wh en t he ther mis tor in the t em per atur e com pe nsa ti on netw ork a nd
the elec t r olyte inside the sensor reach therma l equ ilibrium in appro ximately 45­60 minutes.

Erroneous oxygen readings can result if the gases flowing over the
sensing area of the sens or are not at am bient t em perature. This occ urs

because the sens or is expos ed to dif ferent tem peratur es. The s ensi ng
area of the sensor is o-ri ng seal ed in t h e heat ed breathi ng circ ui t and the tem­perature compensation network at the rear of the sensor is exposed to ambient
temperature.

Effect of Pressure

Electrochemical sensors a ctu all y m eas ure th e par tial pressure, not th e p ercen t­age, of o xy ge n in the gas s t ream they are e xpo sed to. Th es e sensors are a cc u­rate at any press ure provid ed the press ure is cons tant and the analyz er has
been calibrated at the same pressure as the sample gas measured.

For example, when moving an analyzer calibrated at sea level into the moun­tains caus es the anal yzer to display an decre ase in the ox ygen readin g dis­played. When if fact, the decrease in the reading displayed is not related to a
change in the oxygen percentage but to the decrease in partial pressure
(corresponding to the increase in total pressure) at altitude.

Calibrat e at th e temper ature a nd pres sure ( altitu de) at w hich t he ana-

lyzer will be operated.

Effect of Humidity

The an alyzer is no t affect ed by non -condensi ng relativ e humidit y (RH). Ho w­ever, the use of a humidifier to introduce water vapor and increase the mois­ture level of the gas mixture does affect the oxygen concentration and the
resultant reading dis played by t he anal yzer. The addition of water vapor in­creases the total pr es s ure thereby di l uting or decre as i ng the oxygen conce ntr a­tion of the ga s mi xture resulting in a lower oxygen reading.

Effect of Condensati on

Excessiv e co nde nsati on col lecti ng on t he sens ing ar ea or t he el ect ri cal con nec­tions at the rear of the sensors can a dversely imp act the performan ce of elec­trochemical sensors. Conde nsation blocks the di ffusion pat h of oxyg en into th e
sensor a nd ca n re duce t he oxy gen r eading to 00 .0 if the cond ensat ion cov ers
the entire s ensing ar ea. Co ndensation o n t he el ectrical c onnections at the re ar
of the sensor can affect oxygen readings. Remedy either situation by shaking
out the condensation and allowing the sensor to air dry.

Effect of Electromagnetic Radiation

Never operate the analyzer near equipment capable of emitting high
levels of electromagneti c radi at i o n. Do no t continue t o oper ate th e ana­lyzer if the reading becomes unstable.

5.3 Calibration

Calibrating the analyzer or monitor during normal operation involves the same
precautions and procedures as thos e descri b ed in Sections 4 . 7 Start- up Cali bra­tion with the same cautio ns to review Sections 3 S afety Warnings a nd 5.2 Ap­plicatio n Considera t ions.

5.4 Sampling

Assuming the START-UP instructions are followed and the tests are completed
successfully the devices de fault t o the SAMPLIN G mode.

Never operate the analyzer if the reading is unstable or if a malfunction
is suspected. If calibration is required as indicated herein, do not pro­ceed until the analyzer is c alibration succ essfully.

5.4.1 Flowing Gas Stream s

1. Place the sens ing are a of the s ensor i nto the g as str eam to b e analyzed

upstream of any humidification equipment.

2. Assure that the flow rate of the gas stream does not exceed ten (10) liters

per minute. Exceeding ten (10) liters per minute generates backpressure.

3. Check the gas stream and particularly the mechanical connection for leaks

that dilute the gas stream with a mbien t air.

4. Assure there are no restrictions in the circuit downstream of the sensor

that could generate backpressure on the sensor.

5. Use the optional flow diverter along with the op-

tional tee adapter and positi on the s ensor v ertically
for optimum results, as s hown right. The flow di­verter avoids stagnation and facilitates the move­ment of gas to and from the s ensing area of the
sensor thereby producing a more accurate meas­uremen t of the g as stream to be measured.

6. Install the tee-adapter in the breath ing c i rcuit.

7. Screw the flow diverter to the sensor.

8. Ensure the o-ring is lightly lubricated for ease of

entry and a tight seal between the flow diverter and
tee adapter.

9. Insert the assembled flow diverter/sensor into the tee allowing air or

100% oxygen (dry, non-humidified) to fl ow past the sensor at a rate of 5­8 liters per minute.

10. Once th e sensin g area of the se nsor is expose d to the gas stre am allo w

approximately sixty (60) seconds for the reading to stabilize and observe
the reading displayed by the LCD.

11. Refer to Section 8.1 for a variety of accessories that provide a several

methods of sampling flowing gas streams.

5.4.2 Static Atmospheres

Remove the flow diverter, not needed. Failure to remove the flow diverter will
dramatically slow the response time of the sensor.

Expose the sensing area of the sensor to the atmosphere allowing appro xi-

mately sixty (60) seconds for the reading to stabilize and observe the
reading displayed by the LCD.

If placing the entire sensor inside the controlled atmosphere review
