It is widely known that the higher above sea level, the lower the pressure. The higher the pressure, the less changeable the weather. At pressure higher than 1020 mbar, we can expect a dry, clear day. In summer this will simply mean nice weather; in winter, probably a frosty day (though with the possibility of fog). Pressure in the range of 1005–1020 mbar means changeable weather. Periods of clear sky may alternate with passing rain. At pressure below 1000 mbar, the sky will be covered with clouds and we can expect rain. An increase in pressure means improvement, and conversely, a decrease means worsening weather. Sudden, distinct jumps in pressure in summer may indicate severe storms.

A barometer is a very precise device that measures air pressure. For this purpose, it uses a so-called vacuum capsule, whose walls expand or contract by hundredths of a millimeter depending on changing air pressure.

A person feels comfortable at a temperature between 18 and 22 degrees Celsius and at air humidity of 35-65%. We should maintain appropriate air humidity. This is a matter of our health and well-being. It should be remembered that air humidity measured by a hygrometer placed in the home will correspond only to indoor humidity. Outdoors, large fluctuations in humidity occur during the day.

Calibration of the barometer, thermometer, and hygrometer was carried out at the factory. However, as a result of, for example, strong shocks, readjustment may prove necessary. To perform it for the barometer and hygrometer, use a screwdriver and adjust the screw on the rear wall of the device in accordance with the recommendations in the enclosed instructions. In the case of the thermometer, if the mercury column has separated, several sharp jerks will help.

Fischer was founded in 1945 in Drebach, Germany, and has been building barometers, hygrometers, and thermometers there ever since. This represents more than 70 years of experience in this industry. Today, Fischer is a well-known and respected supplier of high-quality products.
