There are two main types of extensometers: contact and non-contact. Contact extensometers have been used for many years and are also subdivided into two further categories. The first type of contact …

This guide helps answer extensometer questions, such as “what is an extensometer?” and “how does an extensometer work?”. If you’re looking to purchase an extensometer, you can view our full range of …

An extensometer is a precision instrument used to measure the deformation, displacement, or elongation of materials when subjected to stress. They are commonly used in material testing …

The long-travel (XL) extensometer is a precise device for measuring strain in highly extensible materials. Designed for use with electromechanical testing instuments, long-travel extensometers can be used …

An extensometer is a precision instrument that measures how much a material stretches, compresses, or deforms when force is applied to it. Some models can detect changes smaller than one millionth of …

Oct 15, 2025 · If you’re familiar with tensile testing, you’ve probably come across a device called an extensometer. In simple terms, extensometers measure how much a material stretches under load.

The extensometer system is supplied with different gauge lengths (gauge length is the distance between two anchors). Several extensometer units can be connected in series to measure incremental …

What is an extensometer? An extensometer is a strain measurement device used to measure the extension of a material under load. The extension of a material is a physical deformation that occurs …

Nov 4, 2025 · An extensometer is a specialized device used in materials testing to precisely measure the physical deformation of a sample under applied mechanical load. This measurement is …
