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.
For measuring the volume flow in the
case of high flow velocities or heavily
contaminated flow, we recommend
the testo440 dP and a Pitot tube.
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.
The testo440 probe system: in ducts, at outlets,
in rooms, at filters or with Pitot tubes.
The 100 mm vane probe can be easily combined
with the 90° angle and telescope, making
measurements at ceiling outlets easier.
All testo440 air velocity probes for measurements
in ducts have a scaled, extendible telescope
(optionally extendible from 1 m to 2 m).
