The 16 mm wired vane probe with integrated temperature sensor is designed for precise air velocity, volume flow, and air temperature measurements in ventilation ducts. With a measuring range of +0.6 to +50 m/s and optimised accuracy above 5 m/s, it delivers reliable results even in demanding applications. The built-in telescope extends to 1.0 m and is clearly scaled for easy immersion depth reading, with the option to add a further extension for total reach of up to 2.0 m (available separately). A fixed cable ensures a stable connection to your compatible Testo multifunction measuring instrument (order separately), while the handle's smart button allows convenient storage of individual readings or timed logging during measurements. Benefit from Testo’s intelligent calibration approach, which keeps your instrument in operation by only requiring the probe to be sent in.
