Product Overview for the Programmable Muffle Furnace

Programmable Muffle Furnace features fast heating and cooling, low energy consumption, precise PID temperature controller with programmable 32 segments. It is an ideal furnace used in laboratory for ashing organic and inorganic samples; heat treating metal parts, stones and ceramics; baking materials and glassware; performing loss on ignition tests; conducting gravimetric analysis, and for the determination of volatile and suspended solids.

Main Features
  • Tmax 1200 °C
  • Furnace used in laboratory, box type, benchtop
  • Dual steel housing with fan cooling for low surface temperature
  • Fiber-insulated chamber for maximum temperature stability and uniformity
  • Embedded heating elements on three sides give an improved temperature gradient
  • Programmable muffle furnace with PID temperature controller 32 segments
  • Type N thermocouple. Equips two pcs, one for temperature testing, the other for protection
  • CE certified, standard
Safety Measures
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • 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
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Application Notes

  • However, toxic or explosive gases that may generate from the sample during the heating are not recommended for use with this programmable muffle furnace without necessary safety controls and supervision.
  • Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
