Description
The testo 420 volume flow hood for larger air inlets and outlets enables fast and precise compliance with hygiene guidelines and requirements concerning indoor 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.
Additional Details
Key Advantages
- Exceptionally light volume flow hood with fast set-up
- Tension rods enable quick, easy set-up of the volume flow hood. The trolley which is included in the scope of delivery ensures safe transport.
- Create protocols directly on site and mail them using the App connection
- Volume flow hood with removable measuring instrument - performance overview
- The volume flow hood for HVAC systems is equipped with a measuring instrument for displaying measurement data. The device can be tilted and removed for user-friendly reading of measuring values.
- The testo 420 measuring instrument enables you to measure flow velocity, volume flow, absolute pressure, temperature and relative humidity. The automatic zeroing ensures higher accuracy for low pressures.
