The Joule heating device utilizes the phenomenon of the Joule effect of conductive materials themselves to apply an electrical environment, causing the materials to reach extremely high temperatures in a very short period of time, in order to investigate the physical properties changes of the materials in extreme environments and severe thermal shock conditions.

1、 Provide an electrical environment for conductive materials and measure their temperature, with a temperature measurement range of 700-3000 ℃;

2、 Provide a high-temperature environment for non-conductive materials (sample stage width 20mm) and measure their temperature up to 3000 ℃.
