I-Tungsten-rhenium thermocouples zezona ziphezulu ze-thermocouples zokulinganisa ubushushu.Ikakhulu ilungele i-vacuum, i-H2 kunye nemeko yokukhusela igesi ye-inert, kwaye ubushushu obuphezulu bokusebenza bunokufikelela kwi-2300 ℃.Kukho iicalibrations ezimbini, i-C(WRe5-WRe26) kunye ne-D(WRe3-WRe25), ngokuchaneka kwe-1.0% okanye i-0.5%
