Testo Hot-wire probe (Ø 7.5 mm, digital) incl. temperature sensor, wired

It is particularly suitable for low to medium flow velocities of up to 20 m/s. At the same time, the measuring probe can also measure temperatures of up to 70 °C. The hot-wire measuring probe is equipped with a telescope that extends to a maximum length of 820 mm. With a small probe head diameter of 7.5 mm, the probe can be excellently used in ventilation ducts with small drill holes. Particularly practical is the ability to change the measuring probe while the measuring device is turned on. Intelligent calibration concept: The probe offers the highest digital measurement reliability. The digital sensor allows for direct measurement processing within the sensor. This technology eliminates device measurement uncertainty. For calibration, the probe can be sent in alone (without the measuring device). By processing the determined calibration data within the sensor, a zero-error display is generated.
