      4.5L Portable PID Control Box Type Muffle Furnace 1800C Lab Using High Temperature Oven


Description of 1800C box type muffle furnace:

Box type muffle furnace is adopted high quality resistance wire as heating element with dual shell structure and intelligent auto-control temperature system, SCR control, phase shifting trigger. The furnace chamber is adopted the 1800 type polycrystalline alumina fiber. Equipped with intelligent cooling system between the dual shell, when the surface temperature reach to 50℃, the cooling fun will be start working automatically, so it can ensure the surface temperature is low; Using constant current soft-start control, to extend the life of heating elements.


Main usage of  box type muffle furnace:

1. In chemical analysis

2. Physical decomposition and synthesis ,superhard materials (such as ceramic)

3. Metal heat treatment of sintering process research and other scientific experiments

4. Universities and colleges ,scientific research institutes

5. Rare and precious metal smelting and purification
