Specifically designed for the highly accurate measurement of strain and deflection, these instruments provide valuable testing information. Extensometers measure strain, which is calculated as the change in length of a specimen divided by the original length (gauge length) of the specimen. Products include extensometers for elongations up to 50% and gage lengths up to 2 inches, extensometers for high temperature or longer gage lengths, extensometers for high elongation, deflectometers and compressometers, bolt extensometers, strain gage extensometers, and video extensometers.
