1400C 1-3 Zone Tube Furnace With Alumina Tube ETL/CE Certified


TF1400 series tube furnaces feature a chamber with Mitsubishi (Japan) high quality alumina fiber insulation and SiC heating elements. A dual-wall steel internal housing helps minimize heat loss to exterior surface.

Furnace operation is controlled by Shimaden (Japan) 40-segment digital controller with built-in RS485 digital communications port and USB adaptor, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results.

  • Compact, portable and lightweight design.
  • Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
  • Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Built-in computer interface.
  • Long life type S thermocouple.
  • ETL and CE certified, standard.


  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions.
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished.

Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
