 Tungsten-rhenium thermocouples were developed to meet the requirements for measuring ultra-high temperatures in the 2760°C (5000°F) range. OMEGA sells 3 widely used tungsten-rhenium thermocouple calibrations: tungsten versus  tungsten-26% rhenium, tungsten-5% rhenium  versus tungsten-26% rhenium, and tungsten-3%  rhenium versus tungsten-25% rhenium. OMEGA® tungsten-rhenium thermocouples conform  to the limits of error listed in the table below. Because of the inherent brittleness of unalloyed tungsten, the tungsten versus tungsten-26% rhenium thermocouples are more difficult to handle than the tungsten-5% rhenium versus tungsten-26% rhenium combination. The average emf of the W-3% Re/W-25% Re is slightly less than that of W/W-26% Re and slightly more than  that of W-5% Re/W-26% Re. The ductility of W-3% Re  is about equal to that of  W-5% Re, but superior to that  of unalloyed tungsten. All 3 thermocouple calibrations can be used to 2760°C (5000°F) in hydrogen or inert gas atmospheres and in  a vacuum. They deteriorate rapidly under oxidizing conditions and should not be used in air or atmospheres containing oxygen. OMEGA tungsten-rhenium thermocouples come  in 300 mm (12") lengths, which corresponds to  each for a 600 mm (24") total length. Longer  lead lengths are available; consult sales.
