Product Description
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 of the overall volume flow on HVAC systems, for instance in hospitals, office buildings or commercial buildings.
High measuring accuracy at swirl outlets thanks to volume flow straightener
Volume flow is frequently measured at swirl outlets. Air flows are often incorrectly measured due to the turbulent air at these outlets.

The testo 420 volume flow hood means you can significantly reduce these measurement errors. The integrated volume flow straightener calms the turbulence and converts it into a virtually uniform air flow. This enables accurate calculation of volume flow in the 80 to 3,500 m3/h range.
Exceptionally light volume flow hood with fast set-up
The volume flow hood with ergonomic handles and tiltable display has an exceptional weight of less than 2.9 kg.
