The testo 440 features unmatched accuracy
for any air velocity range:
Measuring range
Intuitive:
clearly structured measurement
menus for the most important
applications.
Wireless:
Bluetooth
®
probes for more
convenience and less cable
clutter.
Space-saving:
a universal handle for all
probes.
Clear overview:
parallel display of 3 measuring
values; configuration and
results at a glance.
Reliable and secure:
internal memory for up to
7500 measurement protocols,
USB interface for data export,
optional printout of measuring
values.
The testo440 air velocity & IAQ measuring instrument is
available in two versions.
The testo440 dP version also has an integrated differential pres-
sure sensor. This makes measurements at filters as well as Pitot
tube and K-factor measurements possible.
