By combing total enthalpy measurement technique and methods, the principle and characteristic of various total enthalpy measurement methods are presented. The advantage and disadvantage of these methods are analyzed, which include enthalpy probe technique, such as steady enthalpy probe, transient enthalpy probe, mass injection probe and the other enthalpy measurement methods based on energy balance, and optical diagnostics. And the practical experience is given. Finally, the suggestions how to develop the total enthalpy measurement methods better are given based on the above studies.
