Description

UNMATCHED TECHNOLOGY & VALUE

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. Single measurement ranges are available from 0-10 PPM to 0-20,000 PPM with values displayed on a front panel liquid crystal display (LCD). Options include pressure regulators, flow meters, in-line filters, pumps, and block & bleed bypass sampling systems.

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.

NOW FEATURING 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. We offer 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.
