Series 3500/3510

Unmatched Technology & Value

Our ALPHA OMEGA INSTRUMENTS™ Series 3500/3510™ Trace Oxygen Transmitters are designed to provide exceptional performance, accuracy, and stability. The Series 3500/3510™ Trace Oxygen Transmitter is designed to provide accurate and dependable trace oxygen measurements in a variety of background gases. Measurement ranges available are from 0-10 PPM to 0-20,000 PPM.

The Series 3500/3510 enclosure is made from durable polycarbonate and is rated for NEMA 4 (IP 66) service (may change with the addition of certain optional equipment). A 4-20 mADC output is provided that can be used with a data logger, recorder, PLC, DCS, etc. Options include pressure regulators, flow meters, sample filters. The Series 3500 is the loop powered version, and the Series 3510 is the AC powered (115/230 VAC, 50-60 Hz) counterpart and is recommended when AC power is available or preferred. Also, available in optional 24 VDC. In addition to the optional equipment mentioned above, the Series 3510 can be equipped with a sample pump and solenoids valves that can be used for quick gas changes.

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 (may change with the addition of certain optional equipment).

PERFORMANCE

Measurement Ranges: (parts per million) 0-10, 0-50, 0-100, 0-500, 0-1,000, 0-5,000, 0-10,000, and 0-20,000
Accuracy¹: ±1% of full scale (± 5% of full scale on ranges ≤ 0-5 ppm)
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.

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. 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.
