1400 °C box resistance muffle furnace features:
1. Box-type resistance muffle furnace operating temperature: 1300 ° C (short time 1400 ° C).
2. The drop-down door is designed to facilitate loading of the sample.
three. Maximum energy efficiency is achieved by using thermally efficient alumina around the combustion chamber.
Fiber ceramic insulation.
4. Heavy duty double-layer construction with cooling fan. Reduce the case temperature.
5. The PID is automatically controlled by the current limit phase angle to ignite the resistor, such as a thyristor (silicon controlled rectifier).
6. Power control, 30 or 50 segments programmable.
