1. Plural of dilatometer; instruments that measure changes in the volume or dimensions of a material in response to temperature changes or other stimuli.
Usage: technical; scientific

Examples

• The laboratory uses dilatometers to test how metals expand when heated.
• Dilatometers are essential instruments in materials science research.
• The engineers calibrated the dilatometers before conducting the thermal expansion experiments.
• Different types of dilatometers can measure expansion in solids, liquids, and gases.
• The data from the dilatometers showed significant volume changes at high temperatures.
