I. Applications of High and Low Temperature Test Chambers
This equipment is primarily designed for electrical engineers, electronic products, their components, and other materials, to test their adaptability during storage, transportation, and use under high and low temperature conditions. The testing equipment is mainly used to simulate environmental conditions for products in accordance with national standards or customer-defined requirements, testing their physical and other related properties under high and low temperatures. After testing, the performance of the products is evaluated through inspections to determine if they still meet the specified requirements, for product design, improvement, certification, and factory inspection purposes.
