Intuitive climate measurement
Welcome to a new era: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a comprehensive selection of air velocity & IAQ probes. Use it to keep all your air conditioning and ventilation measurements safely and reliably under control.
Intuitive measurement menus
Clearly structured menus for volume flow, K factor, degree of turbulence, heating/cooling output, mould detection and long-term measurement are programmed into the instrument.
Wireless convenience
All the testo 440 probes are also available as wireless Bluetooth versions. This makes for less cable clutter in the measuring case.
Clear display
Measurement configuration and display of readings and measurement results at a glance.
Particularly economical
The testo 440 saves you money:
the measuring instrument does not need to be calibrated, it measures all air velocity & IAQ parameters and the probes can be flexibly extended.
