Thermocouples

Thermocouples are used in various areas. We have therefore divided our thermocouples into sectors for atmospheric and vacuum applications as well as the group of test and sheath thermocouples.

All thermo-control Körtvélyessy GmbH thermocouples combine the highest quality and many years of know-how. They follow the design principles:

  • separate protective tubes
  • additional empty tube for in-situ test measurements
  • pressure aluminum connection head form A
  • standard delivery lengths from 400 mm to 1600 mm

For the technical explanation on the general topic of thermocouples, the pages thermocouples and thermovoltage are available.

We look forward to your inquiry about thermocouples.
