Constant Temperature Humidity Chamber 150L -40C to 150C Environmental Test Chamber
The Constant Temperature and Humidity Unit (also known as a temperature and pressure test chamber or environmental testing machine) is designed to evaluate the tolerance of various materials to heat, cold, dry, and humid conditions. It is widely used for quality inspection across electronic products, electrical appliances, communication equipment, instruments, automobiles, plastics, metals, food, chemicals, building materials, medical devices, and aerospace industries.
