Multi·grafted thermometer is a grafted thermometer composed of a bimetal thermometer and two thermocouples of different kinds.The temperature of the bimetal is so controlled that the temperature difference of the measured body and the bimetal is equal to a set value.In this case, the temperature of the connected portion of the two thermocouples needs not be kept at a set temperature.It is proved theoretically that the temperature to be measured is obtainable by the bimetal thermometer under a set value of the temperature difference.Experiments are carried out with four typical multi·grafted thermometers.The results of experiments show that the temperatures obtained by the trial multi·grafted thermometers agree fairly well with those by a thermoelectric thermometer of the main thermocouple alone with reference temperature of 0°C.
