• Split cover with Interlock protection, cut the power if door open during furnace heating process.

• Fe-Cr-Al Alloy doped by Mo
• Max. heating temperature: 1200°C (N2 or other inert gas must be filled inside the tube to resist deformation)
• Continuously heating temperature: 1100°C
• Heating rate: 20°C /min Ma
• Thermal Couples: K type 220mm (8.7") Length with Ceramic Sheath, please click the link to order spare.

• Total heating zone length: 440mm (~ 18")
• Constant temperature zone: 150mm (+/1°C)
• Please click the image below to view the temperature distribution at 980°C.

     

• FA-YD518P-AG temperature controller is included.
• Proportional–integral–derivative control (PID control) and auto-tune function
• 30 segments programmed with ramping, cooling and dwelling steps
• Built-in over-temperature alarm and thermocouple failure alarm
• +/- 1 ºC temperature control accuracy
• Default DB9 PC communication port
• MET Certified

• MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package is available at the options bar. Click for the detail information about the MTS02-Y software kit. 
  
• You may upgrade the temperature controller to the Eurotherm 3204 Temperature Controller which is fully compatible with LabVIEW. This package includes a Eurotherm 3204 programmer, a communication cable (RS485 - USB) and a software CD. Click the pic below to view the full spec of Eurotherm 3504 temperature controller.           

• Two fibrous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
• Quartz blocks (optional) are ideal for cleaner processing environment and higher vacuum efficiency.
• You may order flange support to avoid tube rotating ( click Pic below right )
  

    

• One pair of SS 304 vacuum flange is included
• Left flange:
• one thermal feedthrough (for 1/4O.D sheathed thermocouple)
• one needle valve
• one mechanical vacuum gauge -0.1Mpa to 0.15Mpa
• one barb fitting ( click PiC, below left-2 for detail)
• Right flange:
• one KF-25 vacuum port  and one needle valve.

        

• An anti-Corrosive gas-type independent (above 10mbar) digital vacuum gauge with a wide range between 3.8x10^-5 to 1125 Torr is optional. Aside from greater measurement precision, this gauge reduces risks of chamber explosions caused by the incorrect reading of gas pressures due to gas-type dependency.

• The flange with quartz window is available for in-situ Raman or Mossbauer analysis

  

• 10E-2 torr by quality mechanical vacuum pump 
• 10E-5 torr by the turbo molecular pump.
• The vacuum pump is optional. Please click here to choose a vacuum pump. 

 

• Brand new laptop with Microsoft Window 10 and Microsoft Office 2013 (30 days free trial) for immediate use.
• Labview Based Temperature Control System (EQ-MTS01) enables user to edit temperature profile, manage heat-treatment recipe, record and plot data for MTI furnaces.
• A wireless remote control provides up to 300 meters operating range.
• Above features are available upon request at an extra cost (up to $1,000). Please contact us for more information.
• Note:  The software is only compatible with MTI’s Yudian Temperature Controller
•     

• Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
• 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.
• Heating module is consumable.  Please click picture below-right to order a replacement.
• The furnace with Sliding flange is available
