The apparatus for measuring rapidly changing temperatures, containing an inertia thermotransducer e. g., a resistance thermometer, a lead network, and differentiating operational amplifiers comprising a calculating device to determine the time constant of the thermotransducer, differs in that, to automatically correct the lead-network time constant with respect to the changing magnitude of the thermotransducer time constant, a magnetizing coil through which passes current proportional to the thermotransducer time constant, is used in the lead-network.
