Testo 440 dP - Differential Pressure, Air Velocity, and IAQ Instrument

Product #4402

Use the testo 440 dP air velocity and IAQ measuring instrument in combination with the high-quality, digital probes to measure and store all air velocity and IAQ parameters (please order probes separately). Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe and a temperature probe with type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier.

A differential pressure sensor is already integrated in the testo 440 dP. This makes it possible to carry out measurements on filters and fans, as well as Pitot tube and K-factor measurements (please order Pitot tube separately).

Product benefits:

  • Intelligent calibration. Only the probes need to calibrate, not the measuring unit.
  • Precise and reliable in ducts, air outlets, monitoring indoor air quality, turbulance, and fume cupboards
  • Wireless Bluetooth® probes for extra convenience when measuring
  • Safe and reliable: internal data storage and USB port for data export
