Zirconia Trace Oxygen FAST Response Analyzer ZRO 2000
Zirconia Trace Oxygen FAST Response Analyzer ZRO 2000 is FAST and 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 ZRO2000 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 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).
It is also 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 ZRO2000 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 ZRO2000 Fast Response Oxygen Analyzer, one for the “Sample Flow” and another for the “Bypass Flow”.
The ZRO2000 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 ZRO2000 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.
