Walk-in Constant Temperature and Humidity Test Chamber
The Walk-in Constant Temperature and Humidity Test Chamber is suitable for conducting accelerated humidity and heat testing, cyclic humidity and heat testing, and constant humidity and heat testing on large components, semi-finished products, electronic and electrical equipment, precision instruments, lithium batteries, chemical products, automotive parts, and pharmaceuticals. It can also be used for constant temperature and humidity storage in warehouses and production under workshop conditions, enabling analysis and evaluation of product performance and behavior under simulated environmental conditions during testing.
