Description

Across International's CF series of muffle furnaces are built for efficiency and economy. Featuring Mitsubishi high quality alumina fiber insulation, the CF series is manufactured for quality. A double walled steel internal housing minimizes heat loss to exterior surface.

Furnace operation is controlled by a Shimaden 40-segment digital controller. Its built-in RS485 digital communications port and USB adapter allows the user to connect the furnace to a Windows PC for remote control and monitoring. All test results and performance can be logged and exported.

Key features of the CF series of muffle furnaces

  • 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 thermocouple -- type K, S, or B (depending on model).
  • CE compliant
  • Optional UL/CSA testing available

Safety

  • 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.
