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. Three sides resistance wire coil for fast and uniform heating.

4. Heavy duty double layer structure with cooling fan. Lower teperature in outside case.

5. 0.5" diameter observation window made of quartz glsss, allows users to see inside chamber during heating operation. 

6. PID automatic control via current limiting phase angle fired the resistor, e.g. SCR(Silicon Controlled Rectifier).             

7. Power control with 30 segments programmable.

8. Vent port (gas outlet) installed on the top for gas flow.
