TRIPLE FUNCTION BAROMETER
Ø30CM

This large instrument combines the three essential pieces of information for atmospheric observation on a single dial: pressure, temperature, and humidity level. With its 30 cm diameter and distinctly contemporary design, it is a centerpiece of the Naudet collection.

At the heart of the device is a barometric mechanism entirely designed and manufactured in our workshop. Developed from our best movement, it offers a precision of ± 1 hPa and also equips some instruments intended for the maritime and scientific fields. The fully mechanical thermometer and hygrometer complete the assembly thanks to their bimetallic operation, without any electrical power. Each device is carefully assembled, calibrated, individually checked, and has its own serial number.

With its 30 cm diameter and 6 cm depth, it offers exceptional readability, even from a distance. It indicates atmospheric pressure in hectopascals (hPa), temperature with a precision of ± 1 °C, and relative humidity with a precision of ± 5 %. It is easily mounted thanks to its keyhole slot on the back.

Its painted brass casing, combined with a chrome-plated brass bezel, a UV-resistant engraved dial, and mineral glass cut in our workshop, gives it a sober and contemporary aesthetic.

Designed to last, this large triple-function barometer embodies the excellence of Maison Naudet's expertise. A true workshop piece, it will accompany its owner for many years and across generations.
