Testo Volume Flow Hood Set 420

The Testo 420 Volume Flow Hood for larger air inlets and outlets enables fast and precise compliance with hygiene guidelines and requirements concerning room air quality. It provides reliable support with the calculation and mesurement of flow velocity, volume flow, absolute pressure, temperature and relative humidity on HVAC systems, hospitals, office buildings or commercial buildings.

Create protocols directly on site and mail them using the App connection. The App enables live measurement on HVAC systems using a start and stop function and the saving of measurement data in txt format. You can then send your readings and protocols via the e-mail function.
