Details

Product Description

Use the hot wire probe (thermal anemometer) to determine flow velocity and volume flow in ventilation ducts or at ventilation outlets. It is particularly suitable for low and medium flow velocities up to +20 m/s. The probe can also measure temperatures up to +70 °C at the same time.

The hot wire probe is equipped with a telescope, which can be extended to a maximum length of 820 mm. The probe is also ideal for carrying out measurements in inaccessible places, since it features a very small probe head (Ø 7.5 mm).
