Temperature and humidity are two indivisible factors in the application of many storage devices, and the temperature effects are different in different regions due to different geographical locations. This test is used to confirm the adaptability of storage products to storage, transportation and use under temperature and humidity climate conditions. The severity of the test, high/low temperature and exposure duration depend on different product applications, product lines and customized requirements.

Yuancun has three product lines, Tianqi (0 ~70 C), Tianyuan (20 ~75 C) and Tianji (40 ~85 C) adapted to different levels of working environment.
