Tungsten-rhenium thermocouples yog cov thermocouples siab tshaj plaws rau kev ntsuas kub. Nws yog tsim nyog rau lub tshuab nqus tsev, H2 thiab inert gas tiv thaiv ib puag ncig, thiab qhov siab tshaj plaws kev ua haujlwm kub tuaj yeem ncav cuag 2300℃. Muaj ob qhov kev ntsuas, C (WRe5-WRe26) thiab D (WRe3-WRe25), nrog qhov tseeb ntawm 1.0% lossis 0.5%
