The main fields of use for humidity measuring equipment lie in the pharmaceutical and food industries, heating, ventilation and air-conditioning (HVAC) applications as well as drying processes and storage. Measurement of air humidity moreover plays a key role in meteorology, while archives and museums also use data loggers or humidity measuring instruments. Apart from humidity, temperature is often also measured. Rotronic humidity measuring instruments therefore usually also measure temperature at the same time.
