Benefits and drawbacks of thermocouple thermometers
Thermocouple thermometers measure temperatures by measuring the voltage induced as a result of temperature differences.
The advantages of thermocouple thermometers are that they:
- can be used to measure high temperatures because metals have high melting points,
- respond very quickly to temperature changes because metals have high conductivities and
- are sensitive to very small changes in temperature.
The main disadvantage of a thermocouple thermometer is that it is less accurate than a mercury thermometer.
