Humidity is the concentration of water vapour in the air.

When working with advanced materials, the stringent control of humidity within defined tolerances is paramount to creating a stable environment.

Potential problems casued by ineffective humidity control:

  • Coatings could dry or cure too fast or too slowly
  • Shorts between connections or layers in electronics applications
  • A low dewpoint can cause a build of up static charges, harmful to some sensitive products

Relative humidity (RH) is a metric of humidity and is dependent on the temperature. It is expressed as a %.
