The Testo 405i is a hot-wire anemometer with a difference; it also functions as a data logger and so can wirelessly interface with your smartphone or tablet via Bluetooth!

Testo's 405i has a fully telescopic anemometer probe shaft, which can be extended up to 400mm. Made for use in professional HVAC work, the multi-directional probe makes it as simple as possible to take airflow readings in the trickiest ducts, shafts and room conditions.

Airflow, velocity and volume flow can be measured using the 405i and wirelessly transmitted to your connected smartphone or tablet to view back readings. By using the free app (available for both iOS and Android), it's possible to use this measurement data to create professional reports, view real-time graphs, send emails to colleagues/customers and much more (see the section below on the app for more information).

The Testo 405i's compact design and folding probe make it a great addition to any toolkit. The probe can be extended up the maximum length and angled up to a complete right angle for use in various different applications.
