• Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature

• Precise: detects the smallest air velocities from as little as 0.1 m/s – ideal for laminar flow measurements in cleanrooms

• Convenient: Bluetooth connection between measuring instrument and probe, with a practical button on the handle for storing individual readings, convenient measurement at ceiling outlets with optional telescope (up to 1 m)

• Intelligent calibration concept

Ideal for air outlets in cleanrooms: use the high-precision vane probe (with the compatible measuring instrument) to measure even the lowest air velocities and volume flows as well as the temperature. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.

• Permanently connected telescopic sensor – maximum length 890 mm, diameter 16 mm
• Airflow measurements, selective and time mean values for calculating air volume
• Hold function; min/max display; auto power off
• Calibration protocol and batteries included
• Vane anemometer with telescopic sensor – ideal for carrying out airflow measurements in air ducts.

The compact 100 mm vane anemometer testo 417 is the ideal solution for simple, fast and precise determination of flow velocity and volume flow at air intake and outlet vents of air conditioning and ventilation systems. Adjustment for balanced residential ventilation or measurement at swirl outlets is also child's play with the testo 417 kits including funnel and flow straightener. Thanks to the connection to the testo Smart App, configuration, display (also as second screen) and storage as well as documentation of the measured values are dealt with quickly and without any complications.
