Hygrometers
A hygrometer is an instrument used for measuring the moisture content in the atmosphere. The components of these measurements include temperature, pressure, mass, or the charge present in a substance as moisture is absorbed. Modern electronic devices use the condensation temperature or electrical resistance changes to measure humidity differences. Hygrometers calculate the relative air humidity to verify desired laboratory conditions and protect materials against atmospheric interference.
