Type S Platinum Thermocouples for L&L Kilns

The Best Thermocouple for High Temperature Use

  • The very best thermocouple for constant high fire applications is a Type S platinum thermocouple with an alumina sheath.
  • Standard on JH Series Kilns.
  • Type S thermocouples are composed of a positive leg which is 90% platinum and 10% Rhodium, and a negative leg which is 100% platinum.
  • At temperatures used in pottery kilns (even the highest 2350°F) these thermocouples can last for a very long time (as long as they are not mechanically broken).
  • The Type S thermocouples that we provide have a 5/16" OD alumina sheath. They are ungrounded. Termination is in a ceramic terminal block.
  • Also available as an option on most kilns.
