Testo 440 speed and indoor air quality (IAQ) measuring device with CO2 probe set helps to assess indoor air quality. The air speed and indoor air quality measurement device, the Bluetooth-enabled CO2 probe and the temperature and humidity sensor are safely stored in the case.

Testo 440 speed and indoor air quality measuring device:

  • Accurate and reliable in ducts and air outlets
  • Performs turbulence measurement according to EN ISO 7730 / ASHRAE 55 standards
  • A wide range of connecting probes is available: with the hot wire and paddle probe (Ø 16 mm), measurements can be made in ducts, and with the large paddle probe (Ø 100 mm) in air/ceiling ventilation systems
  • Automatically calculates the air volume: by entering the cross-sectional dimensions or area of the duct, the air volume measurement value is calculated
  • Takes measurements in extra-large channels: a telescope with a hot-wire and paddle probe (Ø 16 mm) can reach lengths up to 2 metres
  • Takes measurements without the need for a ladder: by attaching a paddle probe (Ø 100 mm) with a retractable telescope, lengths of up to 2 metres are achieved. Also, the vane probe can be folded up to 90°
  • Determines the direction of flow (in or out) in the ventilation grille – using a vane probe, hoods and an airflow straightener
  • Starts or stops measurement, saves data at the touch of a button
  • Attaches to magnetic surfaces with magnets on the back of the device
  • Performs long-term monitoring of indoor air quality
