BK Precision Humidity Meters
Humidity Meters measure the moisture content in the environment by measuring relative humidity, present temperature, dew points, and other parameters. They are used in a variety of applications and come in a variety of styles.

Humidity meters are different from, yet similar to, hygrometers and psychrometers, which measure relative humidity. Humidity refers to the amount of moisture present. Relative humidity is the ratio of the moisture present compared to the amount of moisture needed for saturation.  Hygrometers and psychrometers both calculate relative humidity, while humidity meters measure moisture content by measuring various parameters such as temperature, dew points, and more.
