## U **Calibrated Accuracy Guaranteed** U **Melting Point in Excess of 2315°C (4200°F)** ## **Uninsulated Refractory Metal Thermocouple Wire** Tungsten-rhenium thermocouple alloy combinations were developed to meet the need for measuring ultra-high temperatures in the 2315°C (4200°F) range. OMEGA sells 3 widely used tungsten-rhenium thermocouple alloy combinations: **Type G:** Tungsten (+) vs. Tungsten 26% rhenium (–) - **Type C:** Tungsten 5% rhenium (+) vs. Tungsten 26% rhenium (–) - **Type D:** Tungsten 3% rhenium (+) vs. Tungsten 25% rhenium (–) To guarantee the limits of error, OMEGA[®] sells tungsten-rhenium thermocouple wire only in matched pairs by the double foot. Because of the inherent brittleness of unalloyed tungsten, rhenium has been added to the positive leg of types C and D to improve handling characteristics. The average emf of types C and D is slightly less than that of the unalloyed type G. All 3 thermocouple combinations can be used to 4200°F (2315°C) 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. For other wire sizes and large quantities, consult the Special Quotations department. |**To Order**
