1200C 4-Zone Tube Furnace w/ Touch Screen Controller & Optional Quartz Tube & Flanges (OD 80 -130 mm) - OTF-1200X-IV

  OTF-1200X-IV is a Four-zone split tube furnace that can create a smooth thermal gradient or one uniform constant temperature zone by adjusting the four-zone temperature up to 1200^oC with a 900 mm long heating zone. The furnace includes one quartz tube with optional OD of  80, 100, or 130 mm OD, and one pair of vacuum sealing flanges with pressure gauge & ball valve for immediate use. 
   Touch Screen temperature controller is installed for easy programming with 30 segments and +/- 1 ^oC accuracy. It is an excellent furnace for annealing, diffusing, and sintering samples in various atmospheres.   

Specifications:

Furnace structure	Double-layer steel case with two cooling fans, which ensures a low surface temperature. Energy-saving high-purity fibrous alumina insulation.
Power	AC 208-240V Single Phase, 50/60 Hz (50A breaker required) Power consumption 7 KW Max. A power cord is included without the plug
WorkingTemperature	Max.                          1200  oC < 1 hr. Continuous :               1100  oC  Max. Heating Rate:   <= 20  oC /min
Quartz Tube	Three Types of quartz tubes are available as in the product option  OD 80 x  ID 74 x L 1400  ( mm) OD100 x ID 94 x L 1400 ( mm) OD 130 x ID 124 x L 1400 ( mm)  Two fibrous ceramic tube blocks are included to block heat radiation from inside the tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating) Quartz block (Optional) is ideal for more cleanness and a higher achievable vacuum.
Vacuum -Tight Flange	One pair of the vacuum-sealed flange is included for matched tube The needle valve is installed on the right-side flange with a 1/4" tube fitting The mechanical gauge and valve are installed in the left-side flange Vacuum level: 10-4 torr by turbopump and 10-2 torr by a mechanical pump A digital vacuum gauge (Pic. 1) and KF25 port are available upon request at extra cost   Pic. 1 Pic. 2
Heating Zone Length	Four heating zones:    150+300+ 300+ 150 (mm), in total 900 mm length Constant temperature zone:  300mm within +/- 2 oC (if 4 zones are set at the same temperature)
Temperature Control	Four temperature controllers are integrated into a touchscreen control panel to set temperature profiles easily, which can control each heating zone independently  or heating 4 zones at the same temperature PID automatic control for heating rate, cooling rate, and dwell time up to 30 segments Built-in overheating & broken thermocouple protection. +/- 1 ºC temperature accuracy. Four K-type thermocouples (one for each zone). RS485 Communications Port  and soft are available for PC connection
Compliance	CE Certified NRTL / CSA Certification is available upon request, additional charges will apply
Operation Instruction Click here to learn about the installation of a gas regulator	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 the temperature by yourselves. Please click here to learn how. Warning:  The tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars 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 about 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) to reduce thermal shocks to the tube
