• 
       •  Built-in PID auto-tune function with overheating & broken thermocouple protection

•      •  Over-temperature protection and alarm allows for operation without attendant(s)

•      •  Precise temperature control with less than 1 ℃ temperature fluctuation during dwelling.

•      •  Optional:  

• The furnace may be remotely controlled by a PC by installing a communication module in the controller. 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 software-ready laptop from us
  
  

• 
       •  150mm (+/-1°C) heating area with best temperature uniformity for each heating zone.

•      •  A longer area of temperature uniformity (~ 250mm) can be created by setting both zones at
          the same temperature

•      •  Please click the picture below to view the detail of  temperature uniformity profile at 800°C
  
         
  
  

Flanges & Fittings
(Flange size will be matched with the tube size. Please select in the option bar)

• 
       •  Flanges with 1/4” tube fittings and mechanical valves are included on the both sides.

•      •  Flange fixtures and tube covers are installed to provide additional safety protection in case of
          hydrogen hazards. It is easy to open one side of flange for quick sample loading

•      •  Flange with additional 1/4" themocouple feedthrough is available at an extra cost for in-situ
          temperature calibration and measurements.

•      •  Flange with KF25 port is also available at an extra cost for quick connection with a vacuum
          pump.

•      •  Water-cooled flanges at an extra cost are required if thermal blocks are not inserted.

• 
       •  The tube furnace comes with a pressure gauge and 0 - 1000 ml/min floating flow meter to
           precisely control the overall pressure and flow rate in the quartz tube.

•      •  Two separated gas delivery lines for hydrogen and inert gases.

•      •  The inert gas line comes with a mechanical needle valve.

•      •  The hydrogen line comes with a mechanical needle valve and a solenoid valve controlled by
           the hydrogen gas detector.
  
  

• 
       •  One Honeywell UL Approved Sensepoint Gas Detector is integrated into the system.

•      •  Working Temperature Range: 40ºF to +149ºF (-40ºC to +65ºC)

•      •  Alarm Set Point at 10% (10% LEL). The hydrogen gas delivery line and heating elements will
         be shut down automatically once the alarm is activated.
  
  

•      •  1/4" O.D. stainless steel tube on the right side is installed as a hydrogen torch with a manual
          light to safely burn out the hydrogen exhaust.
  
  

•      •  ~50 kg

•      •  200 lbs

•      •  One year limited warranty with lifetime support.
           The quartz tube as a consumable part is not covered by warranty.

•      •  Attention: A free course of safety operation training at MTI field is required to purchase this
          furnace. A customer's side training is also available upon request at extra cost. If the users
          believe that they have sufficient experience and knowledge to handle the furnace in a
          dangerous situation or emergency, a liability release agreement must be signed at the
          purchase. MTI Corporation is not responsible for any damages caused by misuse without the
          safety operation training. Any damages caused by the corrosive and acidic gases are not
          under the coverage of the MTI One Year Limited Warranty.
  
  

• 
       •  CE Certified

•      •  NRTL or CSA certification at an extra cost. (Please click the marks below to learn details)

• 
       •  Tube furnaces with alumina tubes are designed for using under vacuum < 0.12 atm
          (absolute pressure) and low  positive pressure

•      •  The flow rate of  gases should be < 200 SCCM (or 200 ml/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 below 3 PSI for safe operation. Click here to learn the installation of a gas
         regulator.
         Please note that the regulator for hydrogen gas is different from that for inert gas.

•      •  Quartz tubes may only be safely used up to 1000° under vacuum condition.
