dilatometer

9.3
An instrument that measures how a material changes size when temperature or pressure changes
  • noun
  • /ˌdɪləˈtɑːmɪtər/
  • Specialized
translation icon : dilatómetro
  • The scientist used a dilatometer to measure how the material expanded with heat.

Examples

  • In the laboratory, the dilatometer provided accurate readings of the sample's volume changes.

  • The high-frequency wiggles on the dilatometer and tiltmeter records are solid-earth tides.

    Academic text (2002)
  • By calibrating the dilatometer, researchers ensured precise measurements under varying pressure conditions.

Morphology

dilatometer = dilate (semi-transparent) = dilat + meter

The word is built from the verb 'dilate' and the measuring suffix '-meter', but the specialized scientific meaning is only moderately guessable for an average learner.

Etymology

Dilatometer comes from dilate ('to make wide' or 'spread out') and -meter ('measure'), like in thermometer. So a dilatometer is a device that measures how a material expands or gets bigger, for example when it is heated.
