Humidity - Measurement and Monitoring of relative Humidity


Find out in this short film how relative humidity (RH) arises, how it is measured and why. video not visible? Try this link: - ROTRONIC Relative Humidity Measurement

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.
