Wohler Hygrometers
Hygrometers measure relative humidity. They are often used in homes, offices, and other confined areas. The two main types are digital and analog. They provide accurate measuring and monitoring of temperature and humidity in a wide range of professional and industrial applications such as film processing, printing, hospitals, and laboratories.
Hygrometers are different from humidity meters, which measure humidity based on temperature, dew point, and relative humidity. Humidity refers to the amount of moisture present. Relative humidity is 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.

Types of Hygrometers
-
Digital. Digital hygrometers use non-moving sensors. They record high and low readings.
-
Analog. Analog hygrometers are easy to use and read, are very accurate, and have a fast response time
Key Features of Hygrometers to Consider
-
Datalogger date/time stamps and stores readings on an SD card in Excel® format for easy transfer to a PC Display
-
Multi-parameter measurements
-
Hanging and standing bracket allows flexible positioning on a wall or desktop
This video demonstrates several different hygrometers and discusses some of the key features.
This video discusses the damaging effects of mold, such as structural damage and illness, and how hygrometers can be used to control moisture that causes mold. Key features include the dew point measurement and the humidity alarm that alerts the user when the room reaches specified humidity levels.
