Series 3000

Unmatched Technology & Value

Precision market leading trace and percent oxygen analyzers and transmitters can protect your process, plant and personnel

Our ALPHA OMEGA INSTRUMENTS™ Series 3000™ Trace Oxygen Analyzer is a rugged, microprocessor-controlled oxygen analyzer designed for continuous or intermittent measurement of trace oxygen concentrations.

Range from 0-1 PPM to 0-10,000 PPM
Available in single or three-range configuration.
Auto-ranging for the latter is available at no additional charge

The Series 3000 is housed in a general-purpose enclosure and is powered from either a universal 100-240 VAC, 50-60Hz, or 18-32 VDC. Trace oxygen values are displayed on a 0.4 inch (10.2 mm) high, 4-1/2 digit liquid crystal display (LCD). The Series 3000 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 configurable for fail-safe operation. In addition to the four alarm contacts, the analyzer has a built-in audible alarm and three red LEDs for visual indication of an oxygen alarm condition.

The audible alarm may be manually canceled at any time. The Series 3000 provides users with two standard analog outputs, 4-20 mADC and 0-2 VDC. For enhanced communications, the analyzer can be equipped with optional RS-232C or RS-485 serial communications. Also available with an optional CO2 tolerant sensor.

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 KOH electrolyte can be poisoned from CO2.
Affordable: Economically priced with savings of up to 50% over other manufacturers trace oxygen analyzers.
Wide Measurement Range: Measure from under 1 PPM to as high as 10,000 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.
Visual and audible alarms included along with two analog recorder outputs.

CO2 Resistant Sensor

NEW – 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.

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 configurable 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 LEDs 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 Percent Oxygen Analyzer can be configured with optional RS-232C or RS-485 serial communications. The RS-485 format is capable of sending digital signals over greater distances and controlling each monitor using the same communication channel.

High Performance Trace Oxygen Sensor

The Series 3000 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.
