SUBMARINE BAROMETER Ø125MM - 25

Designed for scientific, technical, and professional applications, this aneroid barometer allows for reliable measurement of atmospheric pressure across a very wide measurement range. It is intended for laboratories, climatological studies, aeronautical intelligence, and any use requiring a robust and precise instrument.

At the heart of the device is a mechanism entirely designed, manufactured, assembled, and calibrated in our workshop. Set to absolute pressure (actual atmospheric pressure), it offers a precision of ± 2.5 hPa. Its thermal compensation ensures an error of less than 0.05 hPa per °C between −10 °C and +40 °C, ensuring excellent measurement stability.

With its 12.5 cm diameter and 5.4 cm depth, it provides a clear reading thanks to its knife-edge needle and high-definition engraved dial. Measurements are expressed in hectopascals, from 700 to 1300 hPa, with a graduation of 2.5 hPa.

It is easily mounted using its mounting 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.

Designed to be portable, it can be taken on an airplane without any special precautions. Each device is delivered with its calibration certificate (manufacturer's certificate). A control certificate can be provided upon request. To preserve its metrological performance, an annual inspection is recommended.
