Muffle Furnace 1400℃ Max.

CE Standard Electric Muffle Furnace 1400℃ Max.
BR-14S high temperature muffle furnace 1400 type consists of high-quality alumina fiber brick and SiC heating elements with a special design. This lab furnace can be used up to 1400℃. It is an ideal electric furnace for materials annealing and sintering in your research laboratory.

Muffle Furnace 1400 type Features

  • Operation Temperature: 1300℃ (1400℃ 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. Lower temperature in outside case.
  • PID automatic control via current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).
  • Power control with 51 segments programmable.
