Testo Hot Ball Probe (Ø 3 mm, Digital, Wired)
The Testo 0635 1051 Digital Hot Ball Probe is a high-precision thermal anemometer designed for non-directional air velocity measurement in undefined or turbulent flow conditions. Its spherical sensor tip (3 mm diameter) makes it ideal for detecting low air velocities up to +10 m/s, even in confined or difficult-to-access areas.
Equipped with integrated temperature measurement and absolute pressure compensation, the probe ensures highly accurate and stable readings. It’s particularly well-suited for applications where airflow direction is variable or unknown, such as comfort-level measurements and indoor air diagnostics.
The extendable telescope (up to 860 mm) enables convenient operation in ventilation ducts, cleanrooms, or laboratory setups. The probe’s digital design processes readings internally, eliminating instrument measurement uncertainty, and its intelligent calibration concept allows for independent calibration—ensuring zero-error display and uninterrupted measurement availability.
