A critical application of the humidity chamber is in the prevention of corrosion and electrical failures. Metals are highly susceptible to oxidation and corrosion when exposed to moisture, especially when combined with high temperatures. Similarly, electronic components and circuit boards can suffer from condensation, leading to short circuits, current leakage, and the growth of conductive metal filaments called dendrites. Testing electronics in a humidity chamber, often following standards like the Highly Accelerated Stress Test (HAST), helps manufacturers identify weaknesses in conformal coatings, seals, and material choices. This proactive approach is vital for producing durable automotive electronics, aerospace systems, and consumer devices that won’t fail in humid conditions.
