Making Use of Hygrometers

Hygrometers are easy-to-use tools for measuring the amount of humidity in the atmosphere. Humidity is the amount of water vapor in the atmosphere that is caused by condensation and evaporation. Humidity affects human comfort and health as well as material possessions. It plays an important factor in heat stroke, heat exhaustion, drying out of furniture, moisture stains, swelling and mold.

The most simple and common way of measuring humidity is through the use of hygrometers consisting of wet and dry bulb psychrometers. Another type which is the mechanical hygrometer uses an organic material such as human hair which either expands or contracts depending on the surrounding humidity. This is the simplest explanation for a bad hair day during hot and humid season.
