We begin with what a thermocouple is and how it works, then walk through how we prepare, weld, and test type K thermocouple wires across a range of temperatures. You'll also learn how matched pairs compare to single legs and how we use international standards to determine accuracy.

Key takeaways:

• What a thermocouple is and how it measures temperature
• How EMF is generated using the Seebeck effect
• The role of hot and cold junctions in sensor function
• Differences between standard and extension grade wires
• What “matched pair” vs “single leg” means, and when to choose which
• Why multi-temperature testing matters for reliability
• How software helps automate and validate EMF results

Whether you’re manufacturing components or working with temperature sensors in high-heat applications, this video gives you a front-row seat to how it’s really done.

Plus, stay for the bloopers at the end. Science doesn’t always go as planned!
