Operation independent of measuring location via your smartphone
The testo 405i hot wire anemometer combines professional Testo measuring technology with App-based operation. This means you benefit from numerous additional functions in your day-to-day work. With the testo Smart App, you can view readings conveniently on your smartphone or tablet. You no longer have to spend ages trying to make out the display at poorly accessible points. Volume flow can also be measured easily using the App: following intuitive input of the duct cross-section, the App calculates this completely automatically.
The App opens up other practical options too: it not only displays measurement data, but also evaluates and documents it. It is easy to carry out a timed and multi-point mean calculation with the App. It also displays the measurement data curve at the press of a button. And sends the measurement data logs as PDF or Excel files.
