Hygrometers are instruments designed to measure the moisture content in the atmosphere, commonly known as humidity. These devices are crucial for monitoring environmental conditions in various settings, including weather stations, greenhouses, museums, and homes. Hygrometers can be analog or digital and they employ different technologies to measure humidity, such as changes in electrical resistance, condensation temperature, or the physical expansion of materials in response to humidity changes. By providing accurate readings of relative humidity, hygrometers help in ensuring optimal conditions for comfort, preserving artifacts, managing agricultural environments and supporting HVAC system efficiency.
