ALPHA OMEGA INSTRUMENTS CORP.
OXY-SEN OXYGEN MONITOR
Alpha Omega Instruments oxygen sensor is designed to operate for prolonged periods of time
without needing replacement. However, in time the sensor's output will drop to a level where
replacement becomes the prudent course of action. A good indication of this is a marked
increase in calibration frequency. When this happens, a replacement sensor should be ordered
directly from the factory.
To install a new sensor follow the directions below:
1.0
Remove AC/DC power from the instrument.
2.0
Locate the sensor cable located on the bottom of the enclosure and unplug the sensor.
3.0
Locate the oxygen sensor where it is mounted and remove the sensor by unscrewing
the sensor by rotating in a counterclockwise motion. Discard the old sensor (see
precautionary note below) and install the replacement sensor being careful not to over-
tighten the sensor. The sensor has an "O" ring seal that when finger tightened, will
provide therequired seal. Reattach the sensor's electrical connector.
4.0
Apply AC/DC power and calibrate according to Section 5.0.
SECTION 6.0
REPLACEMENT OF THE OXYGEN SENSOR
THE SENSOR CONTAINS A SMALL AMOUNT OF WEAK ACID. WHEN
DISCARDING SPENT SENSORS, CARE SHOULD BE GIVEN NOT TO
PUNCTURE THE SENSOR OR TO TAKE IT APART. DISPOSE OF THE
SPENT SENSOR ACCORDING TO LOCAL, COUNTY, OR STATE
GUIDELINES.
