How do you measure humidity in a room without a hygrometer?

Usually, you can measure this with a hygrometer, a simple meter that tells you what percentage of water vapor the air contains. However, if you don't have a hygrometer or you want to figure out the humidity without one, there are other ways. The simplest way is to use wet- and dry-bulb temperatures.

How do you use a hygrometer?

How can we put some numbers to humidity and measure it more accurately? One way is to use an instrument called a psychrometer (also known as a wet- and dry-bulb thermometer). It uses a pair of thermometers standing side by side. One has a bulb open to the air; the other has a bulb covered in a wet cloth.

Where should a home hygrometer be placed?

Using Your Hygrometer You should place it where the humidity symptoms are most obvious, in the room that you are most concerned about, or where your family spends the most time. Because hygrometers are small, they can be moved around in your house from time to time.
