Thermocouple Wire

  • Alloy 405/426 is the combination of compensating alloys (tungsten 5% rhenium vs. tungsten 26% rhenium) used with thermocouples as extension cable
  • Suits high vacuum and ultra-high vacuum applications
  • Sold in 12" increments
  • Each increment of T/C wire includes 12" of both the positive and negative leads
  • Please note, this wire is not welded at the tip creating a "hot junction"

NOTE: These connection wires are used to extend the length of a thermocouple. Actual thermocouples sold separately.

Note: The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of 1 x 10-4 Torr maximum pressure.
