Product Description
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%. The non-depleting sensor used in the Series ZrO2000 Fast Response Oxygen Analyzer is a zirconium type that exhibits fast response times. The analyzer is housed in a NEMA 1 enclosure rated for general purpose use. The front panel contains ve 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 congurable
for fail-safe operation. In addition to the alarm relays, the Series ZrO2000 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 (%).

PERFORMANCE
Measurement Ranges: 0% to 100%
Accuracy: Percent: ±2% of reading or 0.05% absolute whichever is greater.
Trace: ±2% of reading or ±0.5 ppm absolute whichever is greater.
The audible alarm may be manually canceled at anytime. If the audible alarm is canceled and the alarm event continues, indications of this condi-
tion will still be available through the front panel LEDs and relay contact(s). Two ow 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 Oxygen Analyzer comes equipped
with two standard analog outputs. These can be congured for 0-20 mADC 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.
Oxygen Alarm Two (2) SPDT Form C contacts rated
Relays: 10 A @ 30 V DC /115/230 VAC.
Alarms may be cleared manually or automatically, by user selection.
Audible Alarm: Internal audible alarm
NOTE: The sample gas used with the ZRO2000 must not contain any hy­drocarbon vapors, hydrogen, carbon monoxide, or other reducing gases.
Sample tubing should be cleaned for oxygen service. Please consult the
factory for additional information.
Response Time: < 5 seconds at 0.15 liters per
minute (LPM) over 1 decade.
The response time for measurements of less than 50 PPM or less depend
to a great extent on the design of the sample delivery system including the materials used.
