TESTO 405i Thermal Anemometer with Bluetooth

The TESTO 405i is a smart and wireless hot wire anemometer probe designed for measuring air flow velocity, temperature, and volume flow. Equipped with a telescopic shaft that extends up to 400 mm, this instrument allows for easy in-duct testing, enabling users to reliably determine timed and multipoint flow traverses.

Users can conveniently read measurements via the Testo Smart Probes App installed on their smart device. The app provides a powerful and intuitive interface to configure duct dimensions, calculate volume flow measurements, and remotely read data from up to six Smart Probes simultaneously. All measurement data can be displayed as instrument readings, tables, or graphs, and easily saved as PDF or Excel files for straightforward documentation and reporting.

For enhanced functionality, the Testo 405i can be paired with the Testo 605i thermohygrometer to determine cooling and heating performance. Compatible with both Android and Apple OS devices featuring Bluetooth 4.0, it offers flexible and convenient operation across various platforms.
