LBT-125DZR High-Temperature Vacuum Oven for Space Conditions

Description

Product Introduction:

This product conducts thermal cycling tests on specimens under vacuum conditions. It is suitable for use in the aerospace, intelligent manufacturing, new energy, electronic instrumentation, electrical materials, automotive, metallurgical, and electronic product industries, as well as for evaluating the performance characteristics of various electronic components in high‑temperature vacuum environments and for quality management purposes. It is also employed for drying, baking, and heat‑treating materials. In the defense and aerospace sectors, it simulates the vacuum, cold‑black, and solar radiation conditions of space under terrestrial environmental conditions, enabling thermal vacuum and thermal balance tests. Furthermore, it can replicate the extreme thermal conditions of the vacuum environment, allowing for thermal vacuum testing of test articles while providing effective control, monitoring, and recording of their temperatures in a vacuum setting—thus furnishing essential experimental conditions for research on related aerospace products. During simulated testing, specimens are typically operated in their functional states, with both operational and environmental parameters measured.
