Specific Introduction:
KJ-1200X-II-UL is a CE Certified and ready to pass UL/CSA certification (details please refer to the specification below) furnace with optional quartz Tube (60, 80, 100mm) & Vacuum Flanges. Split two-zone tube furnace which can achieve faster heating up to 1200oC and create a different thermal gradient by setting the different temperatures of each zone. The furnace includes one 40" L fused quartz tube with vacuum flanges and valves for immediate use. Two 30 segments of programmable temperature controllers are installed. The microprocessor-based self-tuning PID controller provides excellent control without overshooting the set temperature. It is a perfect tool for CVD applications such as preparing nanomaterials and film.
Parameters:

Furnace structure	Double-layer steel case with two cooling fans, which ensure low surface temperature Energy-saving high purity fibrous alumina liner and insulation High purity Al2O3 coating which provides a longer service life
Power	3 KW (20A Breaker)
Voltage	AC 208-240V Single Phase, 50/60 Hz, a power cord is included without the plug.

Tube Accessories (When the tube size is selected, compatible accessories will match it automatically, please refer to standard package for details)	One fused quartz tube with 1000mm L is included Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) Quartz block (Optional) is ideal for more cleanness and higher achievable vacuum, available at extra cost You may order flange support to avoid tube rotating
Heating Zone Length	Two zones: each zone length 8" (200 mm) Total 16" (400 mm) heating zone
Constant Temp. Zone	150mm (+/-1°C) for each heating zone A longer constant temperature zone ( about 250mm ) can be created by setting both zones at the same temperature
Temperature Controllers	2 MET certified digital controllers with 30 programmable segments for precise control of heating rate, cooling rate and dwell time Built-in PID Auto-Tune function with overheating & broken thermocouple protection Over-temperature protection and alarm allows for operation without attendant(s) +/- 1 ºC temperature accuracy Two K-type thermocouples (one for each zone) RS485 Communications Port Optional: The furnace may be operated by PC by installing a control module. Please order an MTS-02 control module at an extra cost If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop from us

Compliance	CE Certified
Application Notes	Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.Vacuum pressure may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube. Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation. You can set up the different temperature with each zone to create a thermal gradient for CVD deposition
