Ai 1400 40-Segment Muffle Furnace with PC Interface

Category Furnaces
Manufacturer Across International

CF1400 series muffle furnaces feature a chamber with Mitsubishi (Japan) high quality alumina fiber insulation and silicon carbide (SiC) heating elements. A double walled steel internal housing helps minimize heat loss to exterior surface.

Furnace operation is controlled by Eurotherm (UK) or Shimaden (Japan) digital controller with built-in digital communication 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.


  • Controller Option:
    • 3204 can only do 8 segments programmer (ramp and dwelling)
    • 3504 can do 50 segments programmer (ramp and dwelling)
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.
  • 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.
