The Testo 0635 9370 High-Precision 100 mm Vane Probe Head is a specialized digital sensor designed for high-accuracy air velocity, volume flow, and temperature measurements in cleanrooms, laboratories, and controlled environments. Detecting even the smallest air velocities from 0.1 m/s, it is ideal for laminar flow testing, ensuring precise monitoring of airflow uniformity and cleanliness in sensitive applications.
When combined with the universal Bluetooth® or cable handle and, if required, the extendable telescope with a 90° angle adapter (all available separately), this probe head becomes a versatile measurement tool for both duct and ceiling outlet testing.
The high-precision vane sensor ensures repeatable, standard-compliant measurements, while the integrated NTC temperature sensor allows simultaneous monitoring of temperature and flow conditions.
Thanks to Testo’s intelligent calibration system, only the probe head needs to be sent for calibration—keeping your main measuring instrument operational and minimizing downtime.
This modular design is ideal for professionals who already use a Testo universal handle and want to expand their probe portfolio without purchasing a completely new system.
