Series 1000 Oxygen Deficiency Monitor
The Series 1000 Oxygen Deficiency Monitor is an oxygen monitor designed to provide continuous protection from oxygen deficient atmospheres. The Series 1000 Oxygen Deficiency Monitor is a popular choice of government labs, universities, and industrial facilities to help ensure the quality of breathing air. The Series 1000 Oxygen Deficiency Monitor’s primary use is for applications when the possibility exists that breathing air oxygen could be displaced by stored or piped inert gases such as nitrogen, helium, argon, carbon dioxide, etc. resulting in a hazardous condition.

The Series 1000 Oxygen Deficiency Monitor is a microprocessor-controlled instrument with a range of 0-30%. It is powered from 110/230VAC, 50-60Hz, or 18-32VDC. Battery backup is optional. Oxygen values are displayed on an easy-to-read, 10.2 mm (0.4") high, 4-1/2 digit liquid crystal display (LCD). The Series 1000 Oxygen Deficiency Monitor can be equipped with an optional remote sensor enclosure. The oxygen sensor is mounted in a resilient, polycarbonate electronics enclosure. An optional remote sensor enclosure is available for mounting up to several thousand feet from the monitor. In its standard configuration, the electronics enclosure is rated NEMA 1 (IP 30).
The eloquence of the Series 1000 Oxygen Deficiency Monitor is its ease of use. The electronics and optional remote sensor enclosures are equipped with mounting holes molded into each of the four corners for quick and easy installation. The front panel of the Series 1000 Oxygen Deficiency Monitor contains five switches that provide access to the instrument's settings. The Series 1000 Oxygen Deficiency Monitor is equipped with three oxygen alarm relays and one status alarm relay. All four relays are Form C (SPDT) types rated at 10 amps at 110/220VAC and 30VDC.The relays are user configurable for fail-safe operation. In addition to the four alarm contacts, the Series 1000 Oxygen Deficiency Monitor has a built-in audible alarm and three red LEDs for visual indication of an oxygen alarm condition. 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 the relay contact(s).
The Series 1000 Oxygen Deficiency Monitor comes equipped with two standard analog outputs: 4-20mADC and 0-2VDC for use with recorders, dataloggers, etc. For enhanced communications, the Series 1000 Oxygen Deficiency Monitor can also be configured with optional RS-232C or RS-485 serial communications. For multiple point installations, the RS-485 format provides the capability to send digital signals over greater distances and to control each monitor using the same communications channel.
The sensor in the Series 1000 Oxygen Deficiency Monitor has an open diffuser design and does not require a sample pump or aspiration system. Since the extended life sensor is sealed, it does not require an initial charge of electrolyte, or a periodic "topping off" due to evaporation, as do other types of oxygen sensors. Users do not have to handle caustic electrolyte (a hazardous substance).
