What is a hygrometer? A hygrometer is simply a device that measures the relative humidity in the air. A portable hygrometer can be used in any room in your home. Some have multiple sensors so you can monitor the humidity in several areas of your home with only one hygrometer.
If you are asking about a hygrometer, it’s probably because you are concerned about the humidity in your home. Many people are concerned about toxic mold in the home these days, and mold is much more likely to grow in homes with high humidity. Some people also get concerned about the low levels of humidity in the wintertime, because that can cause very dry skin and chapped lips, which can become quite uncomfortable.
There are a couple different types of portable hygrometers. One type of portable hygrometer contains two thermometers, one with a wet bulb and one with a dry bulb. As water from the wet bulb evaporates, the temperature drops. By comparing the difference in temperature between the two thermometers, the relative humidity in an area is determined.
Another type of portable hygrometer actually uses a human hair to determine the level of relative humidity in an area. You may have noticed that some people tend to have “bad hair days” when the weather is particularly humid. That’s because human hair expands and contracts based on the amount of humidity in the air. Hygrometers that use human hairs to measure the relative humidity in an area use a needle gauge to determine just how much the hair expands or contracts and use that information to determine the relative humidity in the area.
Now you know how a portable hygrometer works, but what is a hygrometer used for? Why should you care about the relative humidity in your home? It may surprise you, but excessive humidity can lead to all sorts of problems. It may surprise you even more to learn that insufficient humidity can also cause problems.
Here are just a few of the issues associated with high humidity in the home:
And here are just a few of the issues associated with low humidity in the home:
So if both high and low levels of humidity can cause all these problems, what is a hygrometer reading supposed to be at? Ideally, the humidity in your home should be between 30 and 50 percent to avoid problems.
