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 of the ZRO 2000 makes it ideally suited for industrial applications where continuous oxygen measurements are required. It is available for purchase on our online store.
The ZRO 2000 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 ZRO 2000 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 ZRO 2000 FAST-RESPONSE 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 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 for the ZRO 2000 Fast Response Oxygen Analyzer, one for the “Sample Flow” and another for the “Bypass Flow”.
Our ZRO 2000 FAST-RESPONSE 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. NOTE: Six-digit LCD – the backlit option is no longer available due to supply chain issues.
NOTE: It is essential that the metal sample tubing used to connect to the ZRO2000 be of oxygen service quality (no residual oils or particles on the inner surfaces). In addition, the sample gas should not contain any reducing gases such as any hydrocarbon-based gases, carbon monoxide, or hydrogen. Gases such as these can introduce significant error into the oxygen readings.
