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 LED’s 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 comes equipped with standard RS-232C or optional RS-485 serial communications. – An optional CO2 tolerant sensor. – Made in the USA and priced competitively.
A Long-Lasting Trace Oxygen Sensor
The Series 3000 Trace Oxygen Analyzer features Alpha Omega Instrument’s 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 some electrochemical sensors, Alpha Omega Instruments readings from the Series 3000 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. The long-life trace oxygen sensor is installed in a high integrity-leak tested metal housing that is equipped with 1/4″ stainless steel compression fittings on both the sample gas inlet and outlet. Manual isolation valves are included at no additional charge.
Flexible Configurations for a Range of Uses
The Series 3000 Trace Oxygen Analyzer affords maximum flexibility to meet the increasing demands of the industrial, commercial, and educational markets. It is available in a wide number of optional mechanical configurations. Depending on the application, the Series 3000 can be equipped with a number of options including; sample filters, sample pumps, pressure regulators, block & bleed by-pass sampling systems, serial communications, solenoid valves with internal control connections, flow meters, etc.
A CO2 Resistant Sensor
A nemesis for any conventional “fuel cell” type trace oxygen analyzer is its 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. Alpha Omega Instruments offers 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% carbon dioxide without shortening the life of the sensor.
Made in the USA and Priced Competitively
The Series 3000 Trace Oxygen Analyzer is priced significantly less than most other manufacturers, and it is manufactured as well as quality control tested here in the United States. In fact, our product quality is emphasized throughout the manufacturing process starting with raw material vendor surveys through final assembly, testing, and system calibration. We’ve also earned an exceptional reputation for presale and after-market support for over 25 years.
