Five Zones Split Tube Furnace with 80mm O.D. Quartz Tube & Vacuum Flanges - OTF-1200X-80-V

OTF-1200X-80-V is a CE certified split 80mm OD (3" I.D) Five-zone tube furnace which can achieve faster heating up to 1200oC and create a smooth thermal gradient or one uniform constant temperature zone by adjusting four zone temperature. The furnace includes one 80 mm O.D x 1400mm L fused quartz tube, one pair of vacuum sealing flanges with pressure gauge & ball valve for immediate use. 
Five 30 segments temperature controllers are installed with the K-type thermal couple. Microprocessor-based self-tuning PID control provides excellent control without overshooting and  +/- 1 oC accuracy. It is an excellent furnace for annealing, diffusing and sintering sample in various atmospheres.   Thermo-couple, Power cord and 80 mm O.D. x 55" length, quartz tube and stainless steel sealing flange with gauge/valve are included for immediate use.

Operation Instruction Click here to learn the installation of a gas regulator	Operation Manual       About shipping / Handling    Quick test instruction How to set up the ceramic tube and vacuum flange for MTI Tube Furnace. In order to obtain accurate temperature inside the tube furnace, you need to calibrate temperature by yourselves. Please click here to learn how. Warning:  The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. * Vacuum pressures may only be safely used up to 1000°C   The flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
