INTRODUCTION
The Sper Scientific Oxygen Pen (Model
800047) is designed to read oxygen in
the air.
At standard temperature and pressure,
oxygen is a colorless, odorless,
tasteless diatomic gas with the
molecular formula O2.
Applications for the meter include O2
monitors and detectors, environmental
studies, IAQ, food storage and
refrigeration, bio-technology (oxygen
incubators and anaerobic cultivators),
security systems, air conditioning,
oxygen shortage alarm systems, fire
alarms, and fuel cell systems.

CALIBRATION
For best results, perform the calibration
procedure in a large and ventilated
environment:
Note…
The oxygen value of air (20.9%) is
used for calibration.
1. Press POWER to turn the meter on.
2. Wait at least 3 minutes until the
displayed reading becomes stable
and shows no fluctuation.
3. Press HOLD and REC
simultaneously until “CAL” appears
on the primary display of the LCD.
(The secondary display will show
20.9.)
4. Release HOLD and REC. “CAL will
flash on the LCD for several

seconds, then the meter will return
to Normal Mode, display a value that
is ± 0.1% of 20.9 O2, and complete
the calibration procedure.

MEASUREMENT PROCEDURES
O2and Air Temperature
Measurement
1. Press POWER to turn the meter on.
Note…
Press POWER again to turn the unit off.
2. Point the oxygen/temperature
sensor toward the intended
measurement area.
3. The O2value appears on the primary
display as %O2. The temperature
value appears on the secondary
display as °C or °F.
Hold Function
1. During measurement, press HOLD
to freeze the current readings on the
display. “Hold” will appear on the
LCD.

2. Press HOLD again to release the
hold function.
Record Data
The data record functions holds one
maximum and one minimum reading in
memory. To record:
1. Press REC to start recording. “REC”
will appear on the LCD.
2. With “REC” on the display, press
REC. “REC MAX” and the maximum
value will appear on the LCD.
Note…
To delete the maximum value, press
HOLD. The display will show “REC” on-
ly and the meter will resume exe-
cuting the memory function.

3. Press REC again. “REC MIN” and
the minimum value will appear on
the LCD.
Note…
To delete the minimum value, press
HOLD. The display will show “REC” on-
ly and the meter will resume exe-
cuting the memory function.
4. To exit the data record function,
press REC for at least 2 seconds.
The display will return to the current
reading.
Note…
The maximum and minimum values will
NOT be saved when you exit the
memory function or when the meter is
turned off.

MEASUREMENT PROCEDURES
Setting the Temperature Unit
1. Press POWER to turn the meter off.
2. Press and hold down the HOLD
button. While HOLD is still being
pressed, press POWER until the
temperature unit (°C or °F) appears
on the display. Release the HOLD
button. The temperature unit will
change from °C or °F (or °F or °C).
Note…
The meter will default to the last
temperature unit selected when turned
off and then on again.
Auto Power Off
