Circuitry for ac thermometry and dc heating in measurements of thermal properties

• An instrument is described in which the resistance of a metal wire thermometer is measured by an ac bridge and sampled at a fixed rate. A superimposed dc pulse heats the wire during a selectable time interval. The temperature may be recorded before heating, during heating, and during cooling.
