Beijing Hongda Tianmao Testing Equipment Co., Ltd. is a professional manufacturer of environmental testing and testing equipment. After years of development, it always adheres to scientific and technological innovation and quality service. It has strong production strength and can provide non-standard experimental equipment according to customers' requirements. s solution.
After years of research, our company independently developed and produced the product environmental adaptability testing equipment --- three-box high and low temperature impact test chamber. The equipment is suitable for the safety performance test of electronic components to provide reliability test, product screening test, etc. At the same time, through the equipment test, the reliability of the product and the quality control of the product can be improved. The high and low temperature impact test chamber is an essential test equipment for aviation, automobile, home appliance, scientific research and other fields. It evaluates and determines the parameters and performance of electrical, electronic, automotive electrical, materials and other products after temperature and environmental impact changes in high and low temperature tests. Adaptability to use in schools, factories, military, research positions, etc.
The device has the following structural features:
1. Â Â Â The three-box high and low temperature impact test chamber is all computer controlled. It is a self-developed software with a good operation interface, which makes the operation and monitoring of the user simpler and more intuitive. The maintenance function can keep your running program at present. In the state of this, you can temporarily change the value of this block, Set the time and parameters on the screen to switch between cooling, heating, and blue transfer, and automatically perform the set value.
2. Â Â Â The three-box high-low temperature impact test box is independently controlled by the cold box and the hot box, and the box doors are independent of each other, and the use range of the test box is expanded (one box and three uses).
3. Â Â Â The product insulation effect can be fully guaranteed.
4. Â Â Â The test box door is interlocked with the circulating fan and the blue drive to protect the operator's safety. Once the door is opened, the power of the circulating fan and the blue drive will be automatically cut off.
Products in strict accordance with GB/T2423.1.2-2001 Â Â GJB150.5 Â GB10592-89 related standards are implemented.
