The higher above sea level, the lower the pressure. The higher the pressure, the less variable the weather. At pressure higher than 1020 mbar, we can expect a dry, clear day. In summer, this will simply be fine weather; in winter, the day will probably be frosty (though with a possibility of fog). Pressure in the range of 1005–1020 mbar means changeable weather. Periods of brightness may alternate with passing rain. At pressure below 1000 mbar, the sky will be overcast and we can expect rain. A rise in pressure means improvement, and conversely, a drop means worsening weather. Sudden, pronounced pressure jumps in summer may indicate strong storms.

A barometer is a very precise device for measuring air pressure. For this purpose, it uses a so-called vacuum capsule, whose walls expand or contract by hundredths of a millimeter depending on the 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 proper air humidity. This is a matter of our health and well-being. Please remember that air humidity measured with a hygrometer located 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 sudden jerks will help.

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