INTRODUCTION
This Sper Scientic Datalogging IAQ Meter 800050 is ideal
for measuring indoor air quality in crowded public spaces
with potentially high levels of CO2 (carbon dioxide) such
as o󰀩ces, factories, classrooms, hospitals and hotels.
Recalls the maximum and minimum CO2 readings and
has a user selectable audible maximum alarm. Automatic
Baseline Calibration (ABC) and maintenance free NDIR
(non-dispersive infrared) CO2 sensor ensure long-term
accuracy, stability and reliability. Calibrates to air and
has a hold function. Records up to 32,000 data points of
temperature, RH and CO2 that can be downloaded using a
USB cable and software (included).

ABC CALIBRATION
Connect the AC Power supply to the meter. The meter
defaults to automatic baseline calibration (ABC) when the
unit is turned on. ABC ensures accuracy by eliminating
the zero drift of the infrared sensor. This will automatically
calibrate the meter at the minimum CO2 reading detected
during 15 days of continuous metering.
The ABC is designed for test areas that receive fresh air
with a CO2 level of 400 ppm at some point during fteen
days of metering. If the meter is being used in a closed
area with consistently high levels of CO2, the meter should
be calibrated manually.
MANUAL CO2 CALIBRATION
Note…
Manual calibration is not recommended unless the unit
can be kept in a 400 ppm CO2 environment for at least
12 hours.
1. Set the meter in an area with stable ambient conditions
and no people, or other sources of CO2.
2. Press and hold SET and UNIT for approximately 3

9
seconds. “CAL” will appear on the LCD.
3. The meter will display a countdown from 60, as it needs
60 seconds to calibrate, as well as “400” in the middle of
the screen.
4. Once completed, the meter will reset and the current
readings will now display.
MEASUREMENT PROCEDURES
For the most accurate measurement, do not place the
meter close to any source of CO2.
Note…
Measurement response time is 10 seconds for CO2 and
2 seconds for RH. If the operating environment changes,
it takes approximately 30 seconds for the CO2 sensor to
respond and 30 minutes for the RH sensor to stabilize.
1. Turn the meter ON by pressing PWR.
2. The meter will warm up briey and the reading will
be displayed. Due to the CO2 NDIR sensor, it takes
approximately 10 minutes to get stable readings.
3. To change the temperature scale, press UNIT to cycle
the display between °C and °F.

10
Note…
When CO2 exceeds 1000 ppm, both the alarm (bell) icon
and the red LED will ash a warning. When the CO2 level
falls below this threshold, these visual alarms will stop.
Minimum and Maximum Readings
The meter automatically records minimum and maximum
CO2 levels. To view the minimum and maximum readings
while in Normal Mode:
1. Press MAX/MIN to display the maximum reading.
2. Press MAX/MIN again to display the minimum reading.
3. Press MAX/MIN to return to Normal Mode.
To reset the minimum and maximum readings:
1. With the minimum or maximum reading displayed, press
HOLD for 2 seconds, “0” will display.
2. Press MAX/MIN to return to Normal Mode.
Hold Function
1. Press HOLD to freeze the current reading.
2. Press HOLD again to return to normal mode.
