Electronic DilatometerNonclamping micrometer measures small strains. Electronic dilatometer measures minute dimensional changes caused by moisture absorption in graphite/ epoxy composites. Instrument handles sample 6 inches (15 cm) long and has strain resolution of 0.1 micro-inch/inch (0.1 micron/meter). Possible to predict humidity-induced dimensional changes in items constructed of sample material.
