Surely there are few people who do not show interest in whether the day will be cloudy or sunny. As a rule, when we go outside, we try to look at the sky to try to visually determine if it will rain today or the sun will shine. Need to take an umbrella or not? But will clouds not cover the sky, which will eventually lead to a prolonged rainfall with a thunderstorm?
Perhaps the rain will be accompanied by hail? As you can see, there are a lot of questions on the topic of weather.
Having a barometer is a must
It is in order to make them smaller, and metrology specialists are working: they are constantly engaged in the modernization of apparatuses and devices focused on weather prediction.
And, of course, almost everyone knows about the existence of such a device as a barometer. What is it for? For measuring atmospheric pressure. Based on this, weather can be predicted. Of course, a barometer is a useful thing.
Any person, directly or indirectly, is influenced by atmospheric pressure, since he is on the surface of the Earth. A huge number of people complain of headaches during periods of sharp changes in the above parameter.
Home Weather Station Benefits
The exact number in millimeters of mercury will always be determined by the device we are considering.
A barometer is an indispensable thing for those who spend most of their time on a personal plot. Why? For the proper planting of some plants, it is very important to know the specific value of the pressure in the atmosphere.
Many may say: “Of course, a barometer is a necessary device, but there is television and the Internet.” Well, the age of high technology dictates its conditions. However, many people, as before, prefer to acquire their own home weather station. In addition, the barometer is also a practical thing, since today portable models that are convenient to carry are in high demand.
Types of appliances for home use
Usually everyone uses a home aneroid barometer without mercury. It is completely harmless to human health if damaged. Such a device is made in the form of a small-sized corrugated box, from which excess air is "expelled", and its required amount is used to change the shape of the home weather station. As soon as there is a change in the level of pressure in the atmosphere, the box either expands or contracts.
Forecasts of such weather station models are characterized by maximum accuracy.
There are also mercury devices.
“What is this type of barometer for?” - you may ask. They are also designed to predict the weather. They are made in the form of a tube of glass, from which air is pumped out. The tube is mounted directly above the tank containing the mercury. As the atmospheric pressure level changes, the volume of mercury in the column also becomes smaller or larger.
So, after reading this article, even losers will now be able to answer the question of what the barometer measures. If you want to be the first to own information about the slightest changes in the weather, purchase this useful device for yourself.
