PROFESSIONAL BAROMETER Ø125MM - OVM2

Designed for scientific, technical, and professional applications, this aneroid barometer allows for the precise measurement of atmospheric pressure. Compliant with the P03 2110 A 0000 weather standard, it is intended for laboratories, climatological studies, aeronautical intelligence, and any use requiring a reliable and accurate instrument.

At the heart of the device is a mechanism entirely designed, manufactured, assembled, and calibrated in our workshop. Adjusted to absolute pressure (actual atmospheric pressure), it offers an accuracy of ± 0.7 mbar (± 0.02 inHg). Its thermal compensation ensures an error of less than 0.02 hPa per °C between −10 °C and +40 °C, guaranteeing excellent measurement stability.

With its 12.5 cm diameter and 5.4 cm depth, it offers particularly precise reading thanks to its knife-edge needle and high-definition engraved dial. Measurements are expressed in millibars (845 to 1060 mbar, 1 mbar graduation) and in US inches of mercury (25 to 31.3 inHg, 0.05 inHg graduation).

It is easily mounted using its hanging ring.
For applications subject to vibrations or shocks, it can also be installed on a "Vibrachoc" shock-absorbing mount, specially designed to protect the mechanism while ensuring measurement reliability.
