Product Description

Use the 16 mm vane probe to determine flow velocity or volume flow in ventilation ducts (e.g. during the maintenance, evaluation and commissioning of ventilation systems). It is particularly suitable for medium flow velocities up to +40 m/s and delivers optimum results.

The vane anemometer is equipped with a telescope, so it is convenient to use in larger ventilation ducts too. When extended, the maximum length of the telescope is 890 mm. The immersion depth is easy to read off thanks to the scaling on the telescope.
