What is the hygrometer?
Issue Time:2019-04-03

Hygrometer is an instrument used for measuring the moisture content in the atmosphere.Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation (the dew point), or changes in electrical capacitance or resistance to measure humidity differences. The first practical hygrometer was invented by polymath Johann Heinrich Lambert
