testo 440 Air velocity & IAQ measuring instrument

Welcome to a new era: the new 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 cost-effective
    Save money when using the testo 440: the measuring instrument does not need to be calibrated, it measures all air velocity & IAQ parameters and the probes can be flexibly extended.
