Frequently Asked Questions

How does an aneroid barometer work?

An aneroid barometer uses a small, flexible metal cell that expands and contracts with changes in atmospheric pressure. These movements are amplified by a mechanical linkage to move the dial pointer, providing a direct pressure reading without the need for liquids.

How accurate is this barometer?

This open dial aneroid barometer has an accuracy of ±3 hPa, which is suitable for professional marine navigation and weather monitoring applications. Each unit is individually calibrated during manufacturing.

Can it be mounted outdoors on a ship?

While designed primarily for indoor bridge use, the corrosion-resistant construction allows it to withstand marine environments. However, for prolonged outdoor exposure, additional protective shielding is recommended.

Does it come with a calibration certificate?

Every barometer is factory-calibrated and test-certified to ensure reliable performance. A certificate is included with the product documentation.
