Relative humidity has always been an important factor for the health of humans, animals and plants. We experience relative humidity daily, often without knowing it. Relative humidity plays an important role in not only the comfort of humans, but also the condition of many goods. In many manufacturing processes, products require the correct relative humidity to retain their desired properties.
