Frequently Asked questions
The testo 420 includes a unique, integrated flow straightener. This is a gamechanger for HVAC air flow measurement instruments because it converts turbulent air at swirl outlets into a uniform flow, providing much more accurate readings than traditional hoods.
Yes. The control unit of the testo 420 flow hood is detachable. You can use it as a standalone pressure instrument combined with a Pitot tube to measure the velocity of air flow and differential pressure directly inside ducts.
Absolutely. Via Bluetooth, the testo 420 connects to the Testo Smart App. This allows your smartphone to act as a second display and remote control, enabling you to create and send PDF measurement reports directly from the job site.
The standard testo 420 comes with a 610 x 610 mm hood. However, it is a highly flexible air flow capture hood with several optional interchangeable hood sizes available to fit various commercial and industrial air vents.
Weighing less than 2.9 kg, it is significantly lighter than most volume flow hoods. This reduces technician fatigue during large-scale air balancing projects, especially when performing multiple measurements on high ceilings.
