Specific Introduction:
KJ-1700X-HV furnace consists of a high-temperature alumina tube furnace and a high vacuum system.
It can be heated up to1700°C by a different type of MoSi2 heating elements and achieve vacuum pressure up to 10^-4torr with a diaphragm pump. It is widely used for material or chemical lab to sinter all types of new material samples under vacuum or other gas conditions. The temperature of KJ-1700X tube furnace is controlled by 30 segments programmable high precision SCR power controller with accuracy +/-1°C.

High Vacuum Station	Structure	Mobile cart size: 600 (L) x 600 (W) x 700(H), mm Max. Loading: 600 Lbs on top Molecular pump control Panel: LCD digital Inside: Pfeiffer vacuum pump Vacuum sensor is included
	Vacuum sensor	Two vacuum gauges are installed in this system. 1. Mechanical vacuum gauge 2. High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar) is installed in the whole high vacuum system for monitoring the high vacuum status when operating the furnace with HV station support.
	Control Panel	One button operation - the diaphragm pump and the turbomolecular pump will start after pressing the "start" button. System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber. Self-protection - the system will protect the pump from damage by overheating and over-current if the leaking rate of the reaction chamber is too high to achieve a high vacuum. LCD screen - double lines parameters checking interface make the working easier to be handled.

Note	The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages. The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min ) Vacuum limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
