• Heating Zone: 12 " (300mm), single-zone

• Temperature uniformity:

• 100 mm length (+/-1ºC ): (click drawing below for temp profile)

• 140 mm length (+/-2ºC ): (click drawing below for temp profile)

• PID automatic control via solid-state relay with 30 steps programmable
• Built-in Over Temperature and Thermocouple Failure Protection
• Temperature Accuracy: +/ - 1°C
• Optional: The furnace may be operated by PC with installing a control module. Please order an MTS02-B control module at an extra cost

• 5" flanges with quick load-lock doors for fast sample loading and retrieving. 
• The water-cooled flange is available at an extra cost.
• Left flange assembly:
  • Mechanical pressure gauge
  • Needle valve
  • 1/4" thermocouple feedthrough
  • One 1/4" tube fittings
• Right flange assembly:
  • KF25 port
  • Needle valve
  • One 1/4" tube fittings

• Full tube covers and flange fixtures to avoid hydrogen hazards in case of emergency or explosion. 

• One Honeywell UL-approved sense point gas detector is Integrated into the system.
• Working Temperature Range: -40 ºF to +149 ºF (-40ºC to +65ºC)
• Alarm Point: H2 Lower Explosive Limit (LEL) is set at 20%. Once H2 gas is detected beyond the limit, it will cut off the hydrogen source, turn off the heating elements, and purge nitrogen.
• Power outage protection: if the furnace encounters a power outage, hydrogen source and heating elements will be cut off, and start to flow nitrogen.

•  Two 1/4" compression tube fittings for both inert and flammable gas.
• Interlocks: in case of emergency, the gas flow and furnace heating will be cut off. 
• A flammable gas leak is detected
• Failure of a self-ignition heating coil
• One check valve to prevent gas backflow.

• 50 Kg

• 200 lbs

• 48"x40"x37"

• One year limited warranty for electrical and mechanical parts
• Attention: A free training of safety operation at MTI is required to purchase this furnace. Training at the customer's facility is also available upon request at an extra cost. If users believe that they have sufficient experience and knowledge to handle the furnace in the dangerous or emergent situation, a liability release agreement must be signed at the purchase. MTI Corp. is not responsible for any damages caused by misuse without 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
  

• Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.12 atm (absolute pressure)
• The flow rate for gases should be limited to < 200 SCCM for reducing thermal shocks to the tube
• Attention: A two-stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
• Vacuum limit for all quartz tube furnaces: * furnace operation under vacuum is up to 1000 °C
