Fluke 80PK-1 Bead Probe

The 80PK-1 is a Type-K Bead Thermocouple designed for general purpose temperature measuring applications. It has an extremely fast response time, due to the low thermal mass of the exposed tip. The 40-in Teflon cable is terminated with a Type-K miniature thermocouple connector with 0.312-in pin spacing. The 80PK-1 can be used with any temperature measuring instrument that is designed to accept Type-K thermocouples and that has a miniature connector input.

The 80PK-1 must be used in Teflon-compatible environments and is not suitable for liquid immersion. 


  • Designed to be compatible with any temperature measuring instrument that accepts Type-K thermocouples
  • Miniature thermocouple connector
  • Cold reference junction compensation
  • One year warranty
