The AOI Series 1000 oxygen analyzer is a microprocessor-controlled monitor with an extended-life oxygen sensor mounted in a resilient, polycarbonate electronics enclosure. The sensor has an open diffuser design, and does not require a sample pump or aspiration system. Since the sensor is sealed and does not require an initial charge of electrolyte or a periodic "topping off" due to evaporation, users are not required to handle caustic electrolyte. The monitor can be equipped with an optional remote sensor enclosure, which can be mounted up to several thousand feet from the monitor.
The monitor provides continuous protection of personnel from both oxygen-deficient and oxygen-enriched atmospheres. The monitor's primary use is for environments in which breathing air oxygen could be displaced by stored or piped inert gases such as nitrogen, helium, argon, and carbon dioxide. It is a popular choice for facilities such as government labs, universities, and industrial facilities.
The electronics and optional remote sensor enclosures are equipped with mounting holes molded into each of the four corners for quick and easy installation. Five switches provide access to the instrument's settings, and three oxygen alarm relays and one status alarm relay are user configurable for fail-safe operation. In addition to the four alarm contacts, the monitor has a built-in audible alarm and three red LEDs for visual indication of an oxygen alarm condition.
