The Testo 0635 1026 Digital Hot Wire Probe is a high-precision thermal anemometer designed for accurate air velocity, volume flow, and temperature measurements in ventilation ducts and air outlets. With a probe head diameter of just 7.5 mm, it’s perfect for measuring in small openings or tight duct systems.
This probe integrates temperature measurement and absolute pressure compensation, ensuring stable and accurate flow readings even in varying ambient conditions. The extendable telescope (up to 820 mm) provides flexibility for measuring in deep ducts, while the digital signal processing inside the probe eliminates measurement uncertainty from the connected instrument.
Thanks to Testo’s intelligent calibration concept, the probe can be calibrated independently of the measuring instrument—allowing for a zero-error display and reducing downtime. It can also be changed while the measuring instrument is powered on, offering practical convenience during field work.
