NBD-HP1200-3680TIY high temperature and high pressure furnace, high pressure solenoid valve and pressure sensor are installed on the flange, so when the pressure inside the chamber is higher than the set value, the solenoid valve will automatically open the exhaust, so that the pressure inside the tube reaches the set value. This model can be heat treated under high pressure atmosphere gas environment, the highest temperature can reach 1150℃. It is suitable for the exploration of superconductivity and dielectric materials.
