1500° C tube furnace not only has a refined shape and craftsmanship, but also has a shell that can still be touched safely when the operating temperature is as high as 1400 ° C.Most of the tube furnaces use corundum tubes as the carrier for heating and sealing .The heat transfer is dominated by radiation and the corundum tube is made of opaque material, which will inevitably hinder heat transfer. After more than 200 times of repeated adjustment of the position of the temperature measuring point outside the tube, Our tube furnace 's temperature of measuring point is same with that inside the tube.
