Application of vacuum high and low temperature box products: The vacuum high and low temperature box is mainly used to test the performance of products during storage, transportation, and use in high temperature, low temperature, and humid climate environments. It is mainly used to test the physical and other related properties of electrical and electronic products, components, parts, metal materials, and their materials under simulated high temperature, low temperature, humid and hot climate conditions. After testing, the performance of the product can be judged through calibration to determine whether it can meet the requirements, so as to be used for product design, improvement, calibration, and factory inspection. Product features: Introduction to the structure of vacuum high and low temperature box 01 Adopting a modular structure, the test chamber consists of an insulation box (pressure bearing structure) located at the front, a refrigeration and vacuum unit located at the rear, and an electrical controller (system) located on the door of the test chamber The electrical control panel is placed on the front door of the test chamber for easy operation The refrigeration unit and vacuum unit are placed in separate cabinets to reduce the impact of vibration and noise during the operation of the refrigeration unit on the test chamber, and to facilitate the installation and maintenance of the equipment
