DatenblattThe testo 417 Digital Vane Anemometer offers quick, reliable measurement of airflow, volume flow and temperature at HVAC air inlets and outlets. With App connectivity and optional funnel kits, it’s the go-to solution for precise ventilation assessment and adjustment.
Thanks to seamless integration with the testo Smart App, the testo 417 allows for effortless configuration, real-time display (including a second-screen view on your smartphone), data logging, and automatic report generation—all from a single platform. The App also visualises results with historical graphs and provides a memory function for measurement sessions, greatly improving workflow efficiency.
The testo 417’s ability to automatically calculate time and point average values, as well as volume flow, makes it particularly useful for balanced residential ventilation systems. It enables users to quickly and accurately adjust systems for optimal performance, with full documentation available instantly via the App.
To expand its capability, the testo 417 is available in two tailored kits: Kit 1 includes two measuring funnels for plate outlets and ventilation grilles, covering a variety of air terminal designs. Kit 2 adds a volume flow straightener, perfect for accurate readings at swirl diffusers.
Robust yet portable, and backed by Testo’s engineering quality, the testo 417 is an indispensable tool for HVAC professionals seeking reliable performance and smart functionality in one compact device.
