Abstract

A method of correcting for the non-linearity of thermistor thermometers in calorimetry is described. The correction may either be experimentally determined, or calculated from the thermistor specifications. This system of reducing thermistor data was applied to measurements over temperature differences of several degrees in two different adiabatic calorimeters. A linear temperature resolution of 10 5 to 1 was easily obtainable.
