Barometer: A barometer is a scientific instrument that measures atmospheric pressure (or barometric pressure). Because the Earth has gravity, the air molecules in the layers of the atmosphere stack up and exert pressure, with the air density and pressure increasing as the altitude gets lower to sea level.
Barometers measure the changes in the atmosphere and pressure to determine the weather. A rapid drop in atmospheric pressure means that a low pressure system is nearby, meaning cloudy, windy, rainy, or stormy weather. A rapid increase in atmospheric pressure means the weather is clearing, bringing in cool dry air. The faster the pressure is rising or falling, the faster the weather is predicted to change.
Measuring accuracy barometer: ± 3 hPa
Measuring range barometric air pressure: 970 hPa to 1050 hPa
Thermometer: Helps you keep an eye on the temperature at all times
Measuring accuracy thermometer: ± 1 K, + 1 scale division
Measuring range temperature: -10°C to +50°C
Hygrometer: A hygrometer allows you to measure the humidity and works with either a synthetic fiber or a real strand of hair. Strands of hair expand and absorb moisture as humidity increases, and contract as humidity decreases. This rate of change in the length of hair is constant and can be measured.
Measuring accuracy hygrometer: ± 5% RH (within the range from 20% to 100%), + 1 scale division
Measuring range humidity: 0% to 100%
