testo 440 air velocity & IAQ meter
The new testo440 air velocity & IAQ meter:
versatility in a compact format.
Welcome to a new era: the new testo 440 combines the benefits of a compact handheld device with intuitive measurement
menus and a comprehensive selection of air velocity & IAQ probes. This means you have all measuring tasks on air
conditioning and ventilation systems reliably under control.
Intuitive:
Clearly structured measurement menus for volume flow,
K-factor, degree of turbulence, heating and cooling load,
mold indication and even data logging.
Wireless:
Bluetooth
eliminate the tangle and clutter of cables.
Space-saving:
A universal handle for all probes means more applications,
with less equipment.
Clear overview:
All the essentials combined in a single handheld measuring
instrument.
Simultaneous display of 3 measuring values provides
accurate results at a glance.
Convenience:
Internal memory for up to 7,500 measurement reports, a
USB interface for data export and and optional printout of
all your measuring values.
®
probes offer greater measuring convenience and
The testo440 air velocity & IAQ meter is available in
two versions.
The testo440 dP model includes an integrated differential
pressure sensor. This provides the ability to take
measurements at filters as well as Pitot tube and K-factor
measurements.

suitable for any application.
Based on our many years of experience in the development of cutting-edge measuring technology, we know exactly what
you need to carry out your routine measurements. This is why measurement menus for the essential air conditioning and
ventilation applications are already pre-loaded into the testo440 software. These menus enable you to capture all of your
relevant measuring data quickly, efficiently and most importantly, reliably.

The testo440 probe system: in ducts, at outlets,
in rooms, at filters or with pitot tubes.
All testo440 air velocity probes for measurements
in ducts have a scaled, extendible shaft, optionally
extendible from 3 to 6.5 ft. (1 m to 2 m).
Do you need to carry out measurements in places
where Bluetooth isn't possible? No problem: simply
switch the probe head over from the Bluetooth
handle to the cable handle and you're ready to go
in seconds.
The 4 in. (100 mm) vane probe can be easily
combined with the 90° angle and telescopic
extension, making measurements at ceiling outlets
easier.
With the testo440 dP model, incl. differential
pressure sensor, you can ensure that the filters in
air conditioning systems are working properly. This
confirms no outdoor contamination gets indoors.
For measuring the volume flow in the
case of high flow velocities or heavily
contaminated flow, we recommend
the testo440 dP and a Pitot tube.
