Muffle Furnace 1200℃ Max

High Temperature Electric Muffle Furnace 1200 degree Max.

BR-12N Muffle Furnace uses Resistance wire as heating elements, which can be used up to 1200℃. These compact muffle furnaces are perfect for many applications in laboratory. It is an ideal instrument for materials annealing and sintering in your research.

Muffle Furnace 1200 type Features

  • Operation Temperature: 1100℃ (1200℃ for short time).
  • Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
  • Heavy-duty double-layer structure with cooling fan. The lower temperature in outside case.
  • PID automatic control via the current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).
  • Power control with 51 segments programmable
