1200C 1-Zone Top-Open Tube Furnace w/ Kanthal Element

$4,490.00$18,816.00

Ai STF1200 series top-open tube furnaces feature the famous Kanthal (Sweden) spiral wire coils embedded in Mitsubishi (Japan) high quality grade 1500 alumina fiber insulation. A double walled 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.

Description

Features

  • Compact, portable and lightweight design.
  • Top-open furnace chamber for fast and easy tube access.
  • 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 K thermocouple.
  • ETL and CE certified, standard

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.

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