Abstract This study is to figure out the properties of the DC thermal plasma at low pressure. For this purpose, a temperature measurement system utilizing emission spectroscopy has been set up and its measurement method and results have been described. At low pressure, the plasma has shown drastic changes in its appearance. The discharge characteristics under low pressure have been measured and analyzed. The temperature of thermal plasma generated in this research has been ranged from 10, 000 K to 15, 000 K. Temperature has been observed to increase with the flow rate and magnetic field strength. The temperature characteristics at low pressure has been observed to coincide with the reported results.
