BENEFITS

Provides up to three times the functional life of most “fuel cell” type
sensors. Reliability is dramatically increased while maintenance costs
are reduced.

Eliminates handling potassium hydroxide (caustic), a hazardous mate­rial or having to frequently “recharge” the electrolyte.

Optional CO2 resistant sensor is designed to operate with sample gases
containing up to 100% CO2. Conventional “fuel cell” type sensors using
KOH electrolyte can be poisoned from CO2.

Affords savings of up to 50% over other manufacturers trace oxygen
analyzers.

Measure from under 1 PPM to as high as 10,000 PPM oxygen.

Factory calibration included at no additional charge. Upon request,

NIST calibration certicates available

Ensures the highest level of protection and reliability.

Product Description

The eloquence of the Series 3000 Trace Oxygen Analyzer is its ease of use.

The Series 3000 is a microprocessor- controlled instrument that is avail­able in either a single range or three range conguration. Measurement
ranges are from 0-1 PPM to 0-10,000 PPM. For three range analyzers,
auto-ranging is included at no additional charge. The analyzer is housed
in a general purpose enclosure and is powered from either 115/230 VAC,
50-60Hz, or 18-32 VDC. Battery power is an option. Trace oxygen values
are displayed on a 0.4 inch (10.2 mm) high, 4-1/2 digit liquid crystal display
(LCD). The long-life trace oxygen sensor is installed in a high integrity-leak
tested metal housing that is equipped with 1/4” stainless steel compression
ttings on both the sample gas inlet and outlet. Also included are manual
isolation valves. The Series 3000 can be congured with an optional re­mote sensor that may be placed up to 1,000 feet (approx. 300 meters)
from the electronics. Available in a wide number of optional mechanical
congurations from explosion proof (NEMA 7) to watertight (NEMA 4), the
Series 3000 Trace Oxygen Analyzer affords maximum exibility to meet the
increasing demands of the industrial, commercial, and educational markets.

Depending the application, the Series 3000 can be equipped with a num­ber of options including; battery operation, sample lters, sample pumps,
pressure regulators, data logger, block & bleed by-pass sampling systems,
serial communications, sensor heaters, solenoid valves with internal control
connections, ow meters, etc.

High Performance Trace Oxygen Sensor

The Series 3000 Trace Oxygen Analyzer features Alpha Omega Instru­ment’s long-life ambient temperature electrochemical sensor that has a
functional life of up to three times that of most “fuel cell” type sensors. The
enhanced mechanical design of the sensor ensures longer life, and virtually
eliminates leakage of caustic electrolyte, a nagging (and expensive) prob­lem associated with sensors that require periodic electrolyte maintenance.

Relays: 30 VDC/115/230 VAC. User selectable for fail-

And, because the sensor is sealed, it is not position sensitive. In addition,
unlike some electrochemical sensors, Alpha Omega Instruments readings
from the Series 3000 do not require manual adjustment based on changes
in the molecular weights of the sample gas i.e. helium, hydrogen, etc. a
major advantage for continuous measuring applications. The output from
the sensor is both linear and temperature compensated to provide optimum
performance.

Now Featured a CO2 Resistant Sensor

A nemesis for many conventional “fuel cell” type trace oxygen sensors are
their inability to measure oxygen in gases containing carbon dioxide. Car­bon dioxide reacts with potassium hydroxide electrolyte to form carbonic
acid and in short time destroys the sensor. Not anymore. Alpha Omega
Instruments offers an optional CO2 tolerant trace oxygen sensor with propri­etary electrolyte. The CO2 tolerant sensor is capable of providing accurate
oxygen readings in gases containing up to 100% CO2 without shortening

the life of the sensor.

The Series 3000 Trace Oxygen Analyzer is equipped with three oxygen

alarm relays and one status alarm relay. All four relays are Form C (SPDT)
types rated at 10 amps at 115/230 VAC and 30 VDC. The relays are user
congurable for fail-safe operation. In addition to the four alarm contacts,
the Series 3000 Trace Oxygen Analyzer has a built-in audible alarm and
three red LED’s for visual indication of an oxygen alarm condition. The
audible alarm may be manually canceled at any time. The Series 3000
provides two standard analog outputs, 4-20 mADC and 0-2 VDC. For en­hanced communications, the Series 3000 Trace Oxygen Analyzer can also
be equipped with optional RS-232C or RS-485 serial communications.

The Series 3000 Trace Oxygen Analyzer is priced signicantly less than
most other manufacturers. Before making a purchase decision, we would

be delighted to discuss the Series 3000 Trace Oxygen Analyzer.
