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

The digital probe allows measurement values to be
processed directly in the probe. This technology eliminates
instrument measurement uncertainty.
For calibration, the probe alone (without the hand
instrument) can be sent away.
Calculating the determined calibration data in the probe
generates a zero-error display.

The measurement uncertainty for the relative humidity was calculated
according to GUM and includes hysteresis, dispersion, linearity, repeatability,
uncertainties of adjustment and test site, display resolution. This does not
include the uncertainty values of long-term stability and drift in the case of longterm high humidity measurement.
The measurement uncertainty for CO
was calculated according to GUM and
