        Temperature materials can be provided for eight kinds of conventional thermocouple in the International Electrotechnical Commission (IEC) standards; another developed tungsten rhenium thermocouple material using the upper limit to 2300℃ and Au-Fe thermocouple material using the lower limit to -270℃. In this way, the temperature materials can be produced by covering the entire -271 ~ 2300℃ temperature range.
