1800°C 7x6x6

  • Detailed

KF1800 series muffle furnaces feature a chamber with Mitsubishi (Japan) high quality grade 1900 alumina fiber insulation and the famous Kanthal (Sweden) 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.


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.
