Series 3520 Portable Trace Oxygen Analyzer

Portable, Battery-Operated Trace Oxygen Analyzer with Long-Life Sensor

Our ALPHA OMEGA INSTRUMENTS™ Series 3520™ Portable Trace Oxygen Analyzer is battery-operated and designed for industrial and commercial applications where accurate and reliable spot trace oxygen measurements are needed. The Series 3520 Portable Trace Oxygen Analyzer features long life ambient temperature electrochemical sensor. The enclosure is made from durable polycarbonate and is rated NEMA 1 for general purpose service. The instrument is powered from rechargeable NICAD batteries that are mounted internal to the analyzer.

Recharging of the batteries is accomplished using a built-in battery charger with a universal AC adapter. The Series 3520 comes in a 0-1,000 PPM range (Displays 0-19,999, calibrated in the 0-1,000 ppm range) with values displayed on a front panel liquid crystal display (LCD). It comes with a sample pump and flowmeter with optional filters. Pressure regulators may be purchased separately.

High Performance Trace Oxygen Sensor

The Series 3520 Trace Oxygen Analyzer features our 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. And, because the sensor is sealed, it is not position sensitive. In addition, unlike ome electrochemical sensors, the readings from the Series 3520 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.

INDUSTRIES

Here are some of the industries that use the Series 3520 Portable Trace Oxygen Analyzer:

Oil and Gas: Used in the oil and gas industry to monitor oxygen levels in refining and processing operations.
Chemical: Used in chemical plants to monitor oxygen levels in production processes.
Pharmaceutical: Used in the pharmaceutical industry to monitor oxygen levels in production processes.
Food and Beverage: Used in the food and beverage industry to monitor oxygen levels in packaging and storage environments.
Research and Development: Used in research and development applications to study the effects of oxygen levels on various materials and processes.

FEATURES

Long Life Trace Oxygen Sensor: Provides up to three times the functional life of most “fuel cell” type sensors. Reliability is dramatically increased while maintenance costs are reduced.
Sealed Sensor: Eliminates handling potassium hydroxide (caustic), a hazardous material or having to frequently “recharge” the electrolyte.
Affordable: Affords savings of up to 30% and more over other manufacturers trace oxygen transmitters.
Wide Measurement Range: Measure from 0-1000 ppm (Displays 0-19,999, calibrated in the 0-1,000 ppm range).

SAFETY

We Care About Safety

If you are concerned over unsafe levels of oxygen explore a complete line of oxygen deficiency monitors and accessories. We supply many instruments to medical, aerospace, and municipalities. Occupational Safety and Health Administration (OSHA) defines an oxygen deficient environment when oxygen levels fall below 19.5 percent. Oxygen deficient environments require accurate and reliable instrumentation. Oxygen levels below 16% is dangerous to human life.
