Ai 1700 40-Segment Muffle Furnace with PC Interface

Category Furnaces
Manufacturer Across International

CF1700 series muffle furnaces feature a chamber with Mitsubishi (Japan) high quality grade 1800 alumina fiber insulation and molybdenum silicide (MoSi2) heating elements. A dual-wall steel 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.


  • 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 B thermocouple.
  • CE compliant
  • 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.
