Application
The IAQ probe 0632 1543 is used in conjunction with testo 480 to
measure temperature, humidity, CO
and pressure to evaluate the
2
room air quality.
Observe the information on the measuring process in the
instrument instruction manual.
Notes
• The probe contains sensitive visual components. Please handle
the probe with care.
• Strong vibrations alter the factory calibration. Testing of
measurement values at fresh air 350 to 450 ppm CO
up to 700 ppm CO
).

• If necessary, send the probe to a Testo Service centre for
adjustment. Contact details can be found under
www.testo.com/service-contact
• Avoid dew on the probe to prevent any reduction in its long-term
stability. If there is dew on the probe, this can lead to higher
CO2 measurement values.
• If the ambient temperature changes (change of location,
e.g. indoors to outdoors or vice versa), the probe requires an
adjustment phase of a few minutes.
• When the instrument is switched on, a sensor heat-up phase of
approx. 30 s occurs.
• The CO
concentration in the sensor requires approx. 60 s to
2
adjust to the environment. Gently waving the probe reduces the
equalisation period.
• Keep the probe as far away from your body as possible. This
avoids any influences through the CO2 content of respired air
