Individual adjustment of the barometer to the operating height
The barometer is used to measure the atmospheric air pressure in hPa. The atmospheric pressure can be understood as the weight of a column of air that extends from the surface of the earth to the upper layers of the atmosphere. At sea level, the global average atmospheric pressure is 1013.25 hPa. Mostly it fluctuates between 990 and 1040 hPa.
With increasing altitude, the layer of air above decreases and with it the air pressure, in the vicinity of the earth about 1 hPa per 8 m altitude difference. In order to obtain comparable air pressure values, in weather observation all data are referred to sea level. This means that the pressure actually existing on site (absolute air pressure) is converted to sea level (reduced air pressure).
The barometer is set at the manufacturer's works 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, we adjust it individually to your operating altitude.
