Data sheet

Intuitive: clearly structured measurement menus for the

most important applications stored on the instrument

Wireless: Bluetooth probes for greater measuring

convenience and a reduced tangle of cables in the case

Space-saving: a universal handle for all probes

Clear overview: parallel display of 3 measuring values;

configuration and results at a glance

Reliable: internal memory for up to 7500 measurement

protocols, USB interface for data export and optional

printout of measuring values

measuring instrument

- testo440 dP air velocity &

IAQ measuring instrument incl.

dierential pressure

The 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.

You can connect the testo440 air velocity & IAQ measuring

instrument either to a large selection of digital probes,

the Testo Smart Probes or numerous Testo temperature

probes. Clearly structured menus for measuring volume

flow in ducts/at outlets, K-factor, degree of turbulence,

cooling/heating load, mould indication and logging mode

are stored on the instrument. These menus enable you to

accomplish the relevant measuring task more quickly, more

efficiently and more reliably. Reports can be exported as

Excel files via the USB interface or printed out on site.

The testo440 air velocity & IAQ measuring instrument is

available in two versions. The testo440 dP model version

also has an integrated differential pressure sensor. This

makes measurements at filters as well as Pitot tube and

K-factor measurements possible.
