Versatile and compact. 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.
testo 440 dP:
- Intuitive: clearly structured measurement menus for the most important applications.
- 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.
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.testo 440 16 mm vane kit:
