ZRO2000 Zirconia Oxygen Analyzer

Our ALPHA OMEGA INSTRUMENTS™ ZRO 2000™ 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 is suited for industrial applications where continuous oxygen measurements are required.

The ZRO 2000 Zirconia Oxygen Analyzer is a microprocessor-based instrument designed to measure gas phase oxygen concentrations over a range of 0-100%.  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, it 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 any time. 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, one for the “Sample Flow” and another for the “Bypass Flow”.

Our ZRO 2000 Zirconia Oxygen Analyzer has a measuring range of 0.1 PPM to 100%. Input voltage 90-264 VAC, 50-60Hz has two scalable analog outputs are provided, 4-20 mADC and 0-20 mADC. Included is an easy to read, six-digit backlit LCD as well as two (2) SPDT Form C contacts rated 10A @ 30VDC/115/240 VAC.
