Strain Measurement

In simple terms, Strain is a measure of how a sample changes shape under load. To perform accurate strain measurement, many customers will refer to written standards (ASTM, ISO) which provide detail into the test procedure and the equipment required. United has a wide variety of products which enable our customers to perform accurate strain measurement. From our highly accurate, software driven test frames, to our contact and non-contact extensometers and our sample preparation (die cutting) tools, United has a wide selection of products. In addition, United’s highly educated and well-trained staff can answer many of your questions regarding what equipment should be used for a specific strain measurement application.

United can help you with these and many other testing standards that require measuring Strain, see the machines here
