The testo 416 is a high-precision digital vane anemometer designed specifically for measuring air velocity and volume flow in ventilation ducts. Equipped with a 16 mm cable-connected vane probe, the instrument allows you to perform accurate measurements even in hard-to-reach or overhead ducting, thanks to its telescopic probe that extends up to 850 mm.

Its real advantage lies in its smart functionality. The anemometer connects to the testo Smart App, enabling seamless configuration, real-time measurement viewing, second-screen display, and storage or export of results — all directly from your smartphone. The App also provides visual graphing, history tracking, and easy report generation, improving efficiency on-site.

With automatic time-based and multi-point averaging, the testo 416 ensures you get stable and meaningful readings, especially useful when assessing complex airflow patterns. Its compact size, combined with a durable, rugged housing, makes it suitable for fieldwork in tough conditions.

Whether you're conducting balancing checks, duct testing, or HVAC commissioning, the testo 416 gives you professional-grade accuracy and smart usability, right in your pocket.
