About Barometer

On a barometer, high pressure and low pressure are relative and there is no clear demarcation. However, we can take 1000hPa as the boundary, with low pressure area to the left and high pressure area to the right. Using an adjustable pointer on a barometer lens, you can simply mark the current atmospheric pressure and watch it change. You can read it at least once a day and record how often the pressure changes. Multiple readings a day will give you an accurate weather forecast. Although there are many practical factors that affect weather, such as location, temperature, humidity, wind direction and season, observing changes in atmospheric pressure allows you to make weather forecasts.

Are you still using three instruments to measure air pressure, temperature, and humidity?

However, now there is a three-in-one instrument with a barometer, thermometer, and hygrometer.Barometer weather instrument used to measure air pressure, temperature, humidity and decorative your room.You can pay attention to the change of weather of ever day . The barometer will become one of your favorite indoor outdoor barometer that you like best.
