A recording dilatometer is described in which a resistance strain gauge is used to measure linear thermal expansion. The recording feature is obtained with a conventional recording potentiometer that prints the strain‐gauge output directly, together with the sample temperature. An accuracy of more than ± 0.5% of full scale is attainable.
