PROFESSIONAL BAROMETER - OVM2
Ø125MM

Designed for scientific, technical, and professional applications, this aneroid barometer allows for precise measurement of atmospheric pressure. Compliant with weather standard P03 2110 A 0000, 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. Calibrated for 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, ensuring excellent measurement stability.

With its diameter of 12.5 cm and depth of 5.4 cm, it offers particularly precise readings thanks to its knife-edge pointer and high-definition engraved dial. Measurements are expressed in millibars (845 to 1060 mbar, 1 mbar graduation) and American inches of mercury (25 to 31.3 inHg, 0.05 inHg graduation). It is easily mounted using its suspension ring.
