Our Alpha Omega Instrument OXY-SEN™ Percent Oxygen Monitor is an economically priced percent oxygen monitoring system equipped with a standard measuring range of 0-100%. It comes with dual 4-20 mADC recorder outputs that are scaled over 0-100% and 0-25%. It was designed primarily for applications where the user prefers to mount the gas diffusion end of the sensor through a chamber, glove box, reactor, etc. The diffusion end of the sensor has a threaded stock, providing an easy and convenient way of installing the sensor through the wall of a chamber, glove box, etc. by simply drilling and tapping an appropriately sized hole. Ten feet of coiled interconnecting sensor cable is supplied with each OXY-SEN Percent Oxygen Monitor.
For gas tight integrity, the extended-life sensor is equipped with an “O” ring that helps to form a gas-tight seal. One advantage of using a threaded sensor is that it eliminates the need to use sample pumps or air driven aspirators to provide sample to the sensor. An optional, flow through sensor housing is available for applications where external sampling is 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%. 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 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 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 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 configured 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.
