A temperature and humidity chamber (also referred to as a humidity chamber, climate chamber, or stability chamber) is a controlled-environment test enclosure that independently regulates both temperature and relative humidity. It is used to simulate real-world environmental conditions — from cold storage to tropical heat and humidity — to evaluate how products perform and degrade over time. Temperature humidity chambers are a cornerstone of accelerated life testing (ALT) and HALT/HASS programmes. They are commonly used to meet requirements under IEC 60068-2, MIL-STD-810, JEDEC JESD22, and ICH Q1A pharmaceutical stability guidelines.
