You may have heard your elders sometimes say that “the air is humid” when you feel too hot, and your skin feels too sticky. The air’s humidity means that the air has moisture in it. The higher the amount of moisture, the higher the humidity.
So you may wonder, "How does anybody know if the humidity is higher or lower?" Therefore, a hygrometer device was invented way back in the 1400s by none other than Leonardo da Vinci. Although it has been modified and re-developed by many people, the credit goes to him. The hygrometer measures the relative humidity of the air. Now let us learn more about the hygrometer.
What is a Hygrometer?
As you have learnt above, a hygrometer is a device that measures the relative humidity of the air. You know that everything has some capacity. Similarly, the air has a particular capacity for moisture. Therefore, relative humidity compares the amount of moisture present in the air with the maximum amount of moisture that the air can hold. Hygrometers are used for various purposes.
10 Uses Of Hygrometer
Used To Find the Relative Humidity
As you have already learnt above, relative humidity is all about the amount of moisture in the air concerning its capacity. A hygrometer measures this humidity.
For Measuring Moisture Levels
A hygrometer is used to measure the moisture levels in the air. The measurement of relative humidity helps understand the atmosphere's moisture levels.
Water Vapour in a Mixture of Gases
Suppose a mixture of gases is being used for industrial purposes. Will it always have pure gases? No, because sometimes, water vapour remains, after chemical reactions, in the gaseous mixture. Therefore, measuring the amount is necessary to keep the water vapour levels in check, which is done by the hygrometer.
Used in Various Industrial Processes
The hygrometer is used in industries, especially when something is being produced. humidity levels can alter the nature of the things produced. Therefore, the hygrometer plays an important role in checking the industrial environment's humidity.
Humidity levels are also a part of weather forecasting. Therefore, a hygrometer is used by weather forecasters to give the right information to the viewers.
Saunas are places that are filled with hot steam. People usually go to these places for cleansing and to refresh themselves. Therefore, in such places, temperature and humidity control is significant. Hence, hygrometers are used in saunas to check the humidity levels.
Incubators are where pre-mature babies are kept so they stay in a controlled environment for their care. These incubators also use a hygrometer to check the moisture levels and keep them balanced for the babies.
Used for Wooden Musical Instruments
You must have noticed that in the rainy season, wooden doors and windows usually do not close easily. This is because the wood absorbs the high moisture content of the air. The same happens with wooden musical instruments like violins, guitars, flutes, etc. Therefore, the humidity must be controlled to prevent damage to such instruments. The hygrometer becomes very useful in such places.
Museums contain antique and ancient objects like old manuscripts, etc. The hygrometer is used to check the moisture level in the air, which helps preserve ancient goods.
Used While Preserving Food
Moisture in the air can lead to the growth of microorganisms like fungi in food. This can cause damage to food products, so moisture in the air must be controlled to prevent damage. Hence, hygrometers are used in the food industry to check moisture levels while preserving food.
Isn’t it fascinating that the moisture present in the air can affect our lives in so many ways? And hygrometers play an important role in helping us check the moisture levels and humidity in the air. So, today you have learned about humidity, hygrometers, and the main uses of a hygrometer. You have learnt that hygrometers are devices that help us measure the relative humidity in the atmosphere. As humidity affects many life processes, it is used in industries such as the food industry for controlling the environment's conditions, in hospitals, etc.
