Physiological measurements with the Thermal Head Manikin ALEX II
Test device ALEX II

The 10 zone perspiring heated head form allows the investigation of the thermal and moisture transfer of different headgear.

„ALEX” is placed in a wind tunnel in a climatic chamber. This allows the simulation of desired thermal conditions, with or without the influence of wind. Depending on the article to be examined, the inclination of the manikin head form can be adjusted (wind angle). The size of the head is accordingly with that of an adult person.
