Intuitive: Clearly structured measurement menus for
volume flow, heating & cooling load, K-factor, turbulence,
data logging, mold indication, and more.
Convenient: Testo 440 kits include instrument-specific
wireless and wired probes that offer greater measuring
convenience and the instrument also connects to testo
smart probes.
Space-saving: A universal Bluetooth or wired handle for
all probes means more applications, with less equipment.
Ecient: Internal memory for up to 7,500 measurement
points, a USB interface for data export and optional
printout of all your measuring values.
The testo 440 air velocity and IAQ meter combines all
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.

even a data logging mode are stored on the instrument
for additional convenience. These menus enable you to
accomplish the relevant measuring task more quickly, more
efficiently and more reliably than ever before. Reports can
also be exported as excel files via the USB interface or

You can connect the testo 440 to a large selection of digital
probes, the testo Smart Probes, or even numerous Testo
temperature probes, allowing for numerous configurations
to meet your needs. The clearly structured menus for
measuring volume flow in ducts and at outlets, cooling/
heating load, K-factor, turbulence, mold indication and
The testo 440 air velocity & IAQ meter is available in two
versions. The standard testo 440 and the testo 440 dP
model version, which includes an integrated differential
pressure sensor. This makes measurements at filters as well
as Pitot tube and K-factor measurements possible.

Advantages during measurement
All testo 440 air velocity probes
for measurements in ducts have
an optional scaled, extendible
telescope (extends from 3 to 6.5
feet).
The 4 inch 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
to go.
With the testo440 dP model,
which includes a differential
pressure sensor, you can ensure
that the filters in air conditioning
systems are working properly and
no contamination in the outdoor
air contamination gets indoors.

According to standard EN 60584-2, the accuracy of Class 1 refers to -40 to 1832°F (type K), Class 2 to -40 to 2192 °F (type K), Class 3 to -328 to 104 °F (type K).
A probe only ever complies with one accuracy class.
Information about surface measurement:
• The specified response times t99 are measured on polished steel or aluminium plates at 140°F.
• The specified accuracies are sensor accuracies.
• Accuracy in your application depends on the surface properties (roughness), the material of the measurement object (thermal capacity and heat transfer) and the sensor
accuracy. Testo will produce a corresponding calibration certificate for the deviations of your measurement system in your application. For this, Testo uses a surface test bed
developed in cooperation with the PTB (Physikalisch Technische Bundesanstalt - National Metrology Institute of Germany).
