Testo Hot Wire Probe (Digital, Wired)
The Testo 0635 1032 Digital Hot Wire Probe is a high-precision thermal anemometer designed for accurate measurement of air velocity, volume flow, and air temperature in ventilation ducts. Ideal for HVAC professionals, this smart probe offers reliable readings and effortless operation through intelligent digital processing and an integrated absolute pressure sensor for automatic air density compensation.
The probe’s integrated extendable telescope (up to 0.85 m) with clear scaling makes it easy to perform measurements in ducts of varying sizes and geometries. Its digital design ensures that measurement values are processed directly in the probe, eliminating the uncertainty of instrument-based readings.
With structured measurement menus for volume flow, multi-point and timed mean calculation, and direct display of current, minimum, and maximum readings, the hot wire probe provides both accuracy and convenience. A rotatable protective cap shields the sensitive sensor when not in use, ensuring long service life and measurement reliability.
Testo Hot Wire Probe - Key Features
- Measures air velocity (0–30 m/s), volume flow, and air temperature simultaneously
- Automatic air density compensation via built-in absolute pressure sensor
- Extendable telescope (up to 0.85 m) with scaling for easy duct measurement
- Intuitive measurement menu for volume flow and cross-section geometry input
- Digital probe design eliminates instrument measurement uncertainty
- Rotatable sensor protection cap prevents damage and contamination
- Independent calibration — only the probe needs servicing, not the instrument
- Compatible with Testo multifunction instruments (e.g., Testo 400, 440, 480)
