Unlike a volume flow measuring hood, this measuring device for volume flow measurement can often be employed as a multi-function instrument. The uses of a multifunctional flow meter therefore include volume flow measurement in ducts/at outlets and determination of comfort level or evaluation of illuminance too.
Volume flow measurement via App
With the practical testo 420 App on your smartphone/tablet, you can fully exploit the possibilities of the flow capture hood.
Firstly, this means that you can operate the measuring instrument remotely and secondly, that you can send reports by e-mail directly on site as well.
Overview of the App functions:
- Measuring value monitoring via the testo 420's graphic progression display and remote control
- Creation of reports/documentation with photos or comments and dispatch by e-mail
