The testo440 probe system
Advantages during measurement
Completely versatile: a universal handle for all air velocity
& IAQ probes. This saves space and reduces the weight,
enabling you to perform accurate measurements in any
application.
With the testo440, you have all air conditioning and
ventilation measurements systematically under control.

All testo440 air velocity probes
for measurements in ducts have
a scaled, extendible telescope
(optionally extendible from 1 m
to 2 m).
The 100 mm vane probe can be
easily combined with the 90°
angle and telescope, making
measurements at ceiling outlets
easier.
Do you need to carry out
measurements in places where
Bluetooth isn't possible? No
problem: simply switch the probe
head over from Bluetooth to the
cable handle and you're ready.
With the testo440 dP model, incl.
differential pressure sensor, you
can ensure that the filters in air
conditioning systems are working
properly and no contamination
in the outdoor air gets into the
indoor air.
