Constant Temperature and Humidity Unit
The temperature and pressure test chamber, also known as an
environmental testing machine, is designed to evaluate material
tolerances for heat, cold, dry, and humid conditions. This
equipment is essential for quality inspection across various
industries including electronics, appliances, communications,
automotive, plastics, metals, food, chemicals, building materials,
medical devices, and aerospace.
