Alpha Omega Instruments Zirconia Oxygen Analyzer (ZRO 2000)

  

Alpha Omega Instruments’ The ZRO₂₀₀₀ FAST Response Zirconia Oxygen Analyzer is designed to provide accurate and repeatable trace and percent oxygen measurements in a variety of gases.  Oxygen readings from parts per billion to 100% can be achieved with one instrument. The rugged and compact design of the ZRO₂000 FAST Response Oxygen Analyzer makes it ideally suited for industrial applications where continuous oxygen measurements are required.

The Series ZRO2000 Fast Response Oxygen Analyzer is a microprocessor based instrument designed to measure gas phase oxygen concentrations over a range of 0-100%, and it exhibits fast response times resulting from the non-depleting zirconia oxygen sensor used in the Series ZRO2000 Fast Response Oxygen Analyzer is a zirconia type that exhibits fast response times. The analyzer is housed in a NEMA 1 enclosure rated for general purpose use. The front panel contains five switches that provide access to the analyzer’s settings. Oxygen values are displayed on a 0.7″(17.8 mm) high 6 digit liquid crystal display (LCD). The instrument is equipped with two oxygen alarm relays. Both relays are Form C (SPDT) types rated at 10 amps at 115/230 VAC/ 30 VDC and are user configurable for fail-safe operation. In addition to the alarm relays, the Series ZRO2000 Fast Response our Zirconia Oxygen Analyzer has a built-in audible alarm and red LEDs for visual indication of an oxygen alarm condition. There are also two green LEDs to indicate whether the LCD is displaying parts per million (PPM) or percent (%). The audible alarm may be manually canceled at anytime. If the audible alarm is canceled and the alarm event continues, indications of this condition will still be available through the front panel LEDs and relay contact(s). Two flow meters are standard equipment for the Series ZRO2000 Fast Response Oxygen Analyzer, one for the “Sample Flow” and another for the “Bypass Flow”.

The Series ZRO2000 ​Fast Response Zirconia Oxygen Analyzer comes equipped with two standard analog outputs. These can be configured for 0-20mADC or 4-20 mADC separately. Both are scalable by the user. The analyzer accepts a universal input of 90VAC to 264VAC @ 50-60Hz. The Series ZRO2000 ​Fast Response Oxygen Analyzer incorporates standard features that make it suitable for many applications. However, for certain requirements, the user may desire to augment the capabilities of the instrument by equipping it with a sample pump or pressure regulator.

Made in the USA

The Series ZRO2000 is priced competitively with 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.
