The climate measuring instruments testo 440 combine the benefits of a compact handheld device with intuitive measurement menus and a comprehensive selection of air velocity & IAQ probes. Both the digital Testo Smart Probes and numerous Testo temperature probes can be connected. Clearly structured menus for measuring volume flow in ducts/at outlets, degree of turbulence, cooling/heating load, mould indication and logging mode are stored on the instrument.

USB interface for data export and optional printout of measuring values
Up to 3 probes can be connected
Parallel display of 3 measuring values
Bluetooth probes for measuring convenience and easy storage in the case
Universal handle for all probes
Measurement of the following parameters are possible: °C, % r.h., CO, CO₂, m/s, Lux, hPa

Please order probes separately.
The testo 440 dP also has an integrated differential pressure sensor. This makes measurements at filters as well as Pitot tube and K-factor measurements possible.
