The hot wire probe is equipped with a robust, non-rotatable telescope, which can be extended to a maximum length of 1100 mm. The immersion depth is easy to read off thanks to the scaling on the telescope.
For easier handling, the probe can be bent up to an angle of 90°. On the handle there is a practical measuring button, which activates storage of the readings. So you can fully focus on the positioning of the probe in the ventilation duct.
