Описание: http://www.antiguedadestecnicas.com - This curious item is a dilatometer: a device that calculates the change of volume of the different materials (metals in this case) when heated. It shows an extremely simple though ingenious configuration, being in magnificent condition too. The instrument works fine and is quite attractive; it is made of polished brass, stands on a solid wooden base and mounts a silvery metal scaled arch. It is probably a teaching instrument, though these devices were also used by the factories to calculate the capacity for extension of the different materials.
