Muffle Furnace

Muffle Furnace

1200℃ Muffle Furnace
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.

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