COLLAR HYGROMETER
Ø15CM

for a century to measure air humidity. Entirely designed, manufactured, assembled, and calibrated in our workshop, it bears witness to Maison Naudet's historical expertise.

At the heart of its mechanism is a real human hair. Naturally sensitive to variations in air humidity, it tightens or loosens, and without any electrical power, it moves the needle on the dial from 0 to 100% relative humidity. A mechanical principle of remarkable simplicity, still valued for its reliability.

With a bezel diameter of 12.5 cm, a flange diameter of 15.5 cm, and a depth of 6.6 cm, this hygrometer stands out with its traditional flanged casing, which gives it an authentic and timeless character. The flange allows for elegant mounting using the three mounting screws provided.

The hygrometer offers an accuracy of ± 5%. Each device is carefully calibrated and individually checked in our workshop before being shipped.

Designed to last, this hair hygrometer perpetuates artisanal know-how passed down through several generations and will accompany its owner for many years.
