Testo 420 Volume Flow Hood
A lightweight, precise and convenient instrument, the Testo 420 Volume Flow Hood is the ideal solution for regulating volume flows at larger air intakes and outlets.
Featuring a flow straightener that significantly reduces the usual measurement errors at swirl outlets in particular, the Testo 420 Volume Flow Hood assists users to fulfil hygienic Indoor Air Quality guidelines and stipulations in ventilation and air conditioning systems efficiently (in industry, office rooms or in cleanrooms for example).
Weighing less than 2.9 kg and featuring ergonomic handles, the Testo 420 Volume Flow Hood can be tilted and removed for more comfortable readout of the measurement values.
Mobile devices can also be used as a second display and remote control (via the free iOS/Android Bluetooth App), also letting users finalise and send the measurement report directly on site.
