The industry’s most popular, work-horse carbon probe. Alloy protection tube for versatility and ruggedness. Accepted as an industry standard, around the world.

  • Available in multiple insertion lengths up to 38″ (964mm)
  • 00″ diameter sheath eliminates probe sag problems found on competitor probes – no need to periodically rotate the probe in order to prevent failure
  • Can be inserted up to 10″ inside the furnace – no 4″ limit as found on smaller diameter products
  • Genuine RA330 alloy sheath – we don’t substitute with cheaper alloys like the competition!
  • “K”, “R”, and “S” integral thermocouples are available
  • Fast probe burn-off (90 seconds) and rapid recovery time
  • Probe electrical disconnect allows for simple replacement
  • Strain-relief grommet for direct-to-terminal wiring
