Temperature measurement of high temperature and high velocity gas is very important for a gas turbine combustor development. There are many stuies about the temperature measurement. Particularly, thermocouple method were studied very much, because it is very convenient. But it defect of thermocouple method to cause large error by radiation and conduction to the cold wall around the thermocouple. The conventional method avoid the error by the radiation shield or suction probe. The new concept thermocouple probe is invented, which is designed to contorol the error, not to avoid. The probe was caribrated and applied to temperature measurement of high temperture and high speed gas. The probe can measure the high speed gas temperature ranged 2100Kmax and 590m/smax, accurately.
