Experimenting with Thermocouples. - A-Level Science ...

In Copper-Constantan thermocouples, the smallest temperature change that can be sensed is 1 o C. In some precision measuring applications in industry, this may simply be not accurate enough for the task at hand, such as monitoring a sick person’s body temperature in a hospital, for example, as this would deal in looking at changes in temperature in o C.
