'

Absorption hygrometers, or moisture gauges, are instruments used for measuring the amount of moisture present in the atmosphere. These devices measure the amount of moisture absorbed by a material, such as a sponge or paper, in order to determine the relative humidity of the environment.

Absorption hygrometers use a thermo-hygristor, a special sensor, to measure the amount of moisture being held in the air. The thermo-hygristor works by measuring the change in electrical resistance when exposed to moisture. When the material absorbs moisture, it causes a proportional change in the electrical resistance of the device, allowing it to measure the relative humidity of the atmosphere.

Absorption hygrometers are used in a variety of applications, including heating and cooling systems, indoor air quality monitoring, industrial applications, and the measurement of the amount of moisture in soil. They are also used to measure the level of moisture in the air in agricultural and horticultural settings.

The accuracy and range of an absorption hygrometer depend on its type. Some precision hygrometers can measure humidity levels with an accuracy of up to 0.1 percent. These devices also have a large range, and can measure humidity levels from 0 to 90 percent.

In order to ensure accurate results, it is important to calibrate an absorption hygrometer regularly and keep it clean. Dust and dirt can interfere with the accuracy of the device, so it is important to keep the device away from dust and dirt. It is also important to store the device in a dry, climate-controlled environment to prevent it from becoming damaged by moisture.
