extensometers

An extensometer is a precision instrument used to measure how much a material or object stretches or deforms when force is applied. It helps engineers and scientists understand the strength and flexibility of materials, such as metals or plastics, during testing. By accurately measuring tiny changes in length, extensometers provide valuable data for assessing material properties, ensuring safety, and improving product design. They come in various types, including mechanical, optical, and electronic, each suited for specific testing environments and accuracy requirements.
