1200c muffle furnace is a ce certified high temperature furnace using high quality ceramic fiber board and resistance wire heating elements. The temperature of 1200c muffle furnace is controlled by high precision controller with accuracy +/-0.5 c and 51 segments programmable up to 1200c. This type of furnace is widely used for materials or chemical lab to sinter all types of new materials samples. It is an ideal box furnace for sintering high purity ceramic material at high temperature without element contamination. Muffle furnace features: 1) three sides resistance wire coil for fast and uniform heating serve as heating element 2) maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient high purity alumina fiber ceramic insulation. 3) double layer steel case with air cooling to ensure low surface temperature 4) design of sliding down door is for loading materials easily 5) furnace chamber: 250x320x450mm 6) built in precision digital temperature controller is 51 segments programmable to control heating rate, cooling rate and dwell time. Temperature control unit can be separated from furnace, and make moving at easy. 7) the furnace temperature is controlled by precision scr (silicon controlled rectifier) digital controller with accuracy +/-1c and 51 segments programmable up to 1200c Muffle furnace applications 1.
