Series 3520

Unmatched Technology & Value

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.   

  • Long life ambient temperature electrochemical sensor.
  • Enclosure is made from durable polycarbonate and is rated NEMA 1 for general purpose service.
  • Powered by a rechargeable NICAD batteries that are mounted internal to the analyzer.
  • Recharging 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.

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.
  •  CO2 Resistant Sensor: Optional CO2 resistant sensor is designed to operate with sample gases containing up to 100% CO2. Conventional “fuel cell” type sensors using potassium hydroxide (KOH) electrolyte can be poisoned from CO2.
  •  Affordable: Affords savings of up to 30% and more over other manufacturers trace oxygen transmitters.
  •  Wide Measurement Range: Measure from under 1 PPM to as high as 20,000 PPM oxygen.
  •  Factory Calibration: A factory Certificate of Performance Verification and Calibration is included at no additional charge. The product performance is verified in accordance with manufacturing specifications using a National Institute of Standards and Technology (NIST) traceable transfer calibrated standard gas mix.
  •  NEMA 4 Enclosure Greater installation flexibility with a dust and waterproof enclosure.

PERFORMANCE

  • Measurement Ranges (parts per million) 0-10, 0-50, 0-100, 0-200, 0-500, 0-1,000, 0-5,000, 0-10,000, and 0-20,000
  • Accuracy¹: + 1% of full scale. ¹Stated at constant temperature and pressure
  • Linearity: + 1% of full scale.
  • Response Time: 90% of full-scale response in less than 10 seconds (typical). The response time for ranges of 0-50 PPM or less depend to a great extent on the design of the sample delivery system including the materials used.
  • Sensor Type: Long-life Ambient Temperature Electrochemical Sensor (Optional CO2 Resistant Sensor Available).
  • Temperature Compensation: Standard.
  • Operating Temperature Range: 40° to 104° F (5° to 40° C)
  • Warranty: Two years electronics one year sensor.2 tolerant sensor is capable of providing accurate oxygen readings in gases containing up to 100% CO2 without shortening the life of the sensor.

CONSTRUCTION

  • Enclosure: Polycarbonate rated NEMA 1.
  • Dimensions: 6.5 inches (165.1 mm) height 6.5 inches (165.1 mm) width 7.8 inches (196.9 mm) height Note: All dimensions are without optional equipment
  • Gas Connections: 1/4″ stainless steel compression fittings.

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.
