What is extensometer?

Extensometer is a device that is used to measure changes in the length of the sample during tensile test.

Extensometer model EX53, has a clip-on mechanism. It is connected to either side of the sample and measures increase in the length of the sample.

Ex53 extensometer has an aluminum body and hardened steel blades. With its smooth motion it can give a precision of 1μm.

Extensometer application

With the use of this extensometer the strain-stress curve can be drawn precisely and parameters such as Young modulus, increase in length at yield point, maximum stress and break point can be found.
