PROFESSIONAL BAROMETER -OVM
Ø125MM

Designed for scientific, technical, and professional applications, this aneroid barometer provides accurate atmospheric pressure measurement. It is intended for laboratories as well as climatological studies, aeronautical applications, or any use requiring a high-precision 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 an accuracy of ± 0.5 hPa (± 0.37 mmHg). 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 diameter of 12.5 cm and depth of 5.4 cm, it provides precise readings thanks to its knife-edge pointer and high-definition engraved dial. Measurements are expressed in hectopascals (890 to 1050 hPa in 0.5 hPa increments) and millimeters of mercury (670 to 790 mmHg in 0.5 mmHg increments). It is easily mounted thanks to its suspension loop.

Designed for use between 0 and 700 meters altitude, it can be transported by air without special precautions. Each device is delivered with its calibration certificate (manufacturer's certificate). A verification certificate can be provided upon request. To preserve its metrological performance, an annual check is recommended.
