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 %.
