The box type resistance furnace is specially used for the laboratory of industrial and mining enterprises, universities and research institutes as the analysis of chemical elements and the high temperature heat treatment such as quenching, annealing and tempering of small steel parts; it can also be used for sintering， dissolving, analyzing and other high temperature heating of metal, stoneware and ceramics.

Features:
☆It has high-precision intelligent digital display instrument. The temperature control system adopts microcomputer chip processor, with PID temperature controller, time setting, temperature difference correction, over-temperature alarm and other functions, has high temperature control accuracy. The time setting range is: 0-9999 minutes.
☆The unique furnace door design makes the door opening operation safe and easy, ensuring that the high temperature hot air in the furnace will not leak.
☆The furnace is made of high temperature refractory material to ensure durability.
☆ Excellent door seal minimizes heat loss and increases the uniformity of temperature inside the furnace.
☆The double-layer design of the cabinet shell effectively blocks the internal temperature and reduces the temperature of the shell, achieving energy saving and environmental protection. The panel is made of stainless steel and has the characteristics of corrosion resistance and high temperature invariance.
☆The controller is integrated with the box body. But the bottom case can be pulled out for the convenience of repairing and maintaining.
