The testo 416 Vane Anemometer is a professional handheld device for measuring air velocity and volumetric flow, widely used in HVAC system commissioning, indoor environment monitoring, and industrial ventilation inspection. Equipped with a high-sensitivity vane probe, it accurately captures airflow variations from 0.4 to 20 m/s, delivering reliable data support for field technicians. The ergonomic integrated design combines probe and main unit with slip-resistant grip, enabling one-handed operation particularly suitable for confined spaces or elevated work platforms.

Featuring a high-contrast LCD display with real-time measurement hold function, the instrument ensures clear readability under various lighting conditions. Its auto-ranging capability automatically adapts to velocity changes, minimizing manual adjustment errors. The built-in computing module directly displays volumetric flow data (requires manual duct cross-section input), streamlining field calculations. The wear-resistant composite vane, optimized through aerodynamic design, maintains measurement accuracy while withstanding common environmental factors like dust and humidity.

This anemometer serves multiple professional applications: HVAC technicians can evaluate system efficiency through air outlet velocity measurements; building inspectors may analyze indoor air exchange rates when paired with flow hoods; industrial maintenance teams can verify ventilation equipment performance. Compatible with standard vane probe maintenance procedures, users can perform regular bearing cleaning to ensure measurement consistency. The included protective case safeguards the probe during transport, while the 80-hour battery life supports extended field operations.
