Abstract

The physical parameters inherent in titration calorimetry which limit the temperature resolution of thermistors have been investigated. The individual noise sources were theoretically and experimentally related to the rms temeperature noise by an equation of the form: {A figure is presented} The dependence of A, B. and C on the thermistor resistance, mode and rate of stirring, and the physical boundary between the thermistor and the solution have been investigated. The effects of sampling rate and interval on the measurement of the temperature resolution of thermistors in a d.c. Wheatstone bridge have been evaluated.
