2.3. Alarm
The Analyzer includes an audible alarm that is activated when the sensor reaches a user
programmed minimum % of nitrogen and/or maximum % of nitrogen. The alarm will not clear
until the concentration of N

returns within the parameters programmed by the user. The
alarm function may be activated and deactivated, and must be re-activated every time the
analyzer is powered on.
2.4. Sensor
The Analyzer uses a electrochemical sensor that measures content in gases. The sensor is
disposable and user-replaceable, with a life expectancy of up to 48 months, depending on
usage. The sensor is designed for use at atmospheric pressure (0 psi.). The gas mixture to
be analyzed must be regulated accordingly and any potential for pressure or vacuum must be
avoided.
2.5. Batteries
One 9 volt battery provides power. The battery is located inside the Analyzer and is user-
replaceable. The battery should be removed any time the Analyzer will be stored without use
for extended periods of time. The screen will blink alternately from “000” to “bAt” at start up
when battery is low.
