Relative humidity (RH) is a measure of the quantity of water vapour present in the air. It is important to monitor humidity levels in the manufacturing industry as high humidity levels can result in condensation or corrosion and potentially spoil products. Humidity levels also affect the growth and development of plants, so humidity levels must be monitored in greenhouses.


Relative humidity is measured using a Thermohygrometer, and Hanna supply a variety of products that are ideal for determining the relative humidity.
