The Testo 0635 9571 Bluetooth Vane Probe is a precision-engineered digital sensor for accurate measurement of air velocity, volume flow, and air temperature in ventilation ducts. With its wireless Bluetooth® connectivity, this probe ensures maximum measurement flexibility, reduced cable clutter, and effortless data transfer up to 20 meters away from the instrument.
Designed for HVAC professionals and field engineers, the vane probe measures air velocity up to 50 m/s with exceptional accuracy, making it suitable for both low and high-flow applications. The integrated temperature sensor allows simultaneous monitoring of thermal conditions, enabling a complete understanding of ventilation system performance.
The extendable telescope (up to 1.0 m) features a high-contrast scaling for easy depth reading, even in low-light conditions. For large ventilation systems, it can be extended up to 2.0 m using an optional telescope extension. The ergonomic handle includes a practical button for direct measurement control—store readings, start or stop measurement series, or capture multi-point averages with ease.
The intelligent calibration concept allows calibration directly on the probe, eliminating the need to return the measuring instrument, such as the Testo 400, 440, or 480, for servicing. This ensures zero-error display and continuous productivity.
