Abstract

A computer-controlled adiabatic calorimeter for use in the continuous warming mode was designed, constructed, and tested. Since its intended use was in measuring the singularities in specific heats near critical solution temperatures, a thermometric sensor capable of yielding accurate values of T at very slow temperature scan rates was required. A pyroelectric thermometer was selected for the purpose. Details of the design of the calorimeter, the pyroelectric thermometer, the platinum resistance thermometer, and the computerized data acquisition and control system are presented. Preliminary measurements of the singularity of the specific heat of the triethylamine-water system are discussed.
