using thermoelectric elements, e.g. thermocouples

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Measuring temperature based on the use of electric or magnetic elements directly sensitive to heat > using thermoelectric elements, e.g. thermocouples

CPC:

Measuring temperature based on the use of electric or magnetic elements directly sensitive to heat (giving results other than momentary value of temperature G01K3/00) > using thermoelectric elements, e.g. thermocouples

Of 9 combined children, 5 exist in both systems.

4 codes are CPC-only extensions.
