Individual barometer adjustment for measurements at high altitudes

Barometer mechanism for use above 900 meters including individual adjustment of the barometer to operating altitude.

The barometer is used to measure atmospheric pressure in hPa. Air pressure can be understood as the weight of a column of air extending from the earth's surface to the upper layers of the atmosphere. At sea level, the global average atmospheric pressure is 1013.25 hPa. Predominantly, it fluctuates between 990 and 1040 hPa.

With increasing altitude, the overlying air layer and thus also the air pressure decreases, near the earth about 1 hPa per 8 m difference in altitude. In order to obtain comparable air pressure values, all data in the weather observation are related to sea level. This means that the pressure actually present on site (absolute air pressure) is converted to the level of sea level (reduced air pressure).

The barometer is set at the manufacturer's factory for the altitude indicated on the packaging. Only in rare cases will it be possible to use the barometer without readjustment.

To ensure that your barometer is immediately ready for use at altitudes above 900 meters, we provide it with a special altitude measuring mechanism and adjust it individually to your operating altitude.

Please enter your location altitude in the field "Comment/Location altitude" in the last step of the purchase process.

If your location is below 900m NN you can order a normal barometer adjustment: Indiviual Barometer Adjustment
