Abstract
A high temperature extensometer system carries specimen contact rods of substantial length which pass through openings in a furnace to engage a specimen in such furnace. The rods are supported at the exterior of the furnace on a paralleogram linkage support frame made to provide an output indicating specimen strain as the contact rods separate and also made with parallel beams which shift so the rods can move differentially in longitudinally axial direction. The rods shift axially when the specimen and test loading grips shift in position, for example when the grips and specimen are initially heated.
