1700℃ hydrogen reduction CVD system can be used for vacuuming and filling atmosphere, so it is also called vacuum tube furnace and atmosphere tube furnace. The tube is made of a seamless high purity alumina and the maximum working temperature is up to 1650℃. In order to match the test requirements for the introduction of hydrogen, the tube furnace is equipped with a manual ignition device at the right end of the furnace tube to ensure the safety of the test; a vacuum gauge and an air pressure gauge are arranged on the left side of the furnace tube to control the vacuum and atmosphere inside the furnace tube. Further safety of the test is ensured by the interlocking of the solenoid valve and the pressure sensor and the flammable gas detection device.
This system also includes a two-channel float flow meter with a stainless steel needle valve and an air pressure gauge to accurately mix the gas that meets the test requirements. Under normal circumstances, this set of instruments is used with a double stage rotary vane vacuum pump to achieve a general low vacuum test environment. If you need a higher vacuum, you can contact our technicians to select a more powerful molecular pump.
The device is widely used in materials or chemical laboratories to sinter various new material samples under hydrogen or hydrogen-nitrogen mixed gas conditions.
