testo 440 – combined pressure and airflow measurement kit with Bluetooth

This measurement set includes the testo 440 dP ventilation and indoor climate meter. It can be connected to a wide range of digital sensors, testo SmartProbes and many other temperature sensors. In addition to the features of the testo 440, this instrument has an integrated differential pressure sensor. Thanks to it, you can also perform measurements over filters and use Pitot tubes (Prandtl tubes). The instrument has clearly structured measurement menus for duct/vent volume flow, k-factor, turbulence degree, cooling/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.

Avoid cable clutter thanks to the universal handle with Bluetooth. This is a practical and affordable measurement kit for all relevant parameters in ventilation ducts and air vents/roof vents. The instrument, vane wheel and hot wire sensor are extremely easy to use and very handy when adjusting ventilation systems. The calibration concept is also very intelligent. You only need to send in the sensor part for calibration, so you can keep the handle and the instrument.

Included in delivery

  • The testo 440dP multi-instrument
  • Universal handle with Bluetooth
  • Hot wire sensor incl. temperature and humidity sensor
  • Vane wheel sensor with 100 mm diameter. incl. temperature sensor
  • Telescope (1 m) and 90° angle to fit both sensors
  • Combination case for testo 440 dP and multiple sensors
