Humidity Testing

humidity testing

Humidity testing is typically performed in a chamber that can precisely control wet and dry temperatures.  Exposing products to humidity stress precipitates corrosion and contamination defects in products.  Humidity can penetrate porous materials, cause leakage between electrical conductors, and is also an important stress when evaluating coating and seals.

Typically, humidity tests are of long duration, and certain types of corrosion require minimal airflow, which is not typical of most chambers.

Result: an effective means of detecting moisture penetration in porous materials, detecting leakage between electrical conductors, and evaluating coatings and seals.
