Thermocouples are temperature sensors known for their fast thermal response time, low cost, and wide measurement range.

This application note covers thermocouple topics such as fundamental theory of operation, device selection, advantages and limitations, setup and measurement using LabJack hardware, and troubleshooting.
If you are measuring temperatures in the range of -50 to +150 °C, consider using a silicon-based temperature sensor rather than a thermocouple. See the Temperature Sensors application note.
Thermocouples have poor inherent accuracy, but high resolution measurements are possible. Understand the difference between resolution and accuracy.
