High Temperature Vacuum Furnace

High-temperature vacuum furnaces provide the controlled environment required to test materials under heat and vacuum conditions. Their main components include a vacuum system, a heating chamber, temperature measurement and control equipment, and a water-cooling system. Each part controls a different aspect of the test environment, from the vacuum level and heating conditions to temperature monitoring and equipment cooling.
