Features:
• Less than 2.9 kg weight
• Flow straightener for more precise measurement at swirl outlets
• Removable and tiltable measuring instrument with a large display
• App integration via Bluetooth for fast and easy monitoring and reporting on site
Applications:
- HVAC
- Ventilation
- Air Conditioning
- Office rooms/cleanrooms
Overview:
The testo 420 Volume Flow Hood is the light, precise and convenient solution for regulating volume flow at larger air inlets and outlets. At swirl outlets in particular, the flow straightener significantly reduces the usual measurement errors. This allows users to fulfil hygienic Indoor Air Quality guidelines and stipulations in ventilation and air conditioning systems quickly and precisely, e.g. in industry, office rooms or in cleanrooms.
Handling is especially easy with a uniquely low weight of less than 2.9 kg and ergonomic handles. The Volume Flow Hood can be tilted and removed for more comfortable readout of the measurement values. The app connection enables mobile devices to be used via Bluetooth as a secondary display, for customer and measurement data management and as a remote control. This makes using a tripod for high ceilings, for example, especially safe and comfortable. Moreover, the user can use the app to finalise and send the measurement report directly on site.
