Humidity indicator with white dial and black bezel. It is made of bimetal and has a diameter of 100mm.
It perspires through the holes in the lower part of the crown and allows it to be hung on the wall through a support on the back.
To calibrate it, it is recommended to use a damp cloth covering the breather and wait for the needle to rise to 80% humidity. Remove the cloth and the needle will drop until graduation at that time.
