ABSTRACT:
A temperature measurement apparatus comprising a temperature sensitive device such as thermistor and a reference resistor of small temperature coefficient of resistance, which are alternatively connected to an electric circuit which produces an output signal responding to change of resistance, and the apparatus comprises a memory which memorizes a reference output signal by a reference resistor at a predetermined reference environmental temperature and a reference voltage of a power source, and a calibration is made to a measured temperature value by use of said memorized reference output signal.
