Designed for easy clip-on attachment, these versatile high elongation extensometers are available in gage lengths of 0.5, 1, or 2 inches. With measurement capabilities to 1000% sample elongation, these unique extensometers also feature built-in over load protection.

To accommodate most testing requirements, the EZ extensometer can be used on either round or flat samples. Each comes with two special features: a built-in overload protection and the automatic gage length setting which helps ensure a high degree of consistency between the users and the testing samples. Special gage lengths are also available upon request. Available in both room and high temperature versions, the EZ Extensometer is accurate to ± 0.0001 (Class B1) as per ASTM-E83.

Takes measurements from both sides of samples and averages the results. Available in gage lengths of 5, 1, 1.4, or 2 inches. Built-in overload protection. Automatic gage length setting. High temperature version to 350 D. F. available. Meet the accuracy requirements of ATM E-83 Call B-1

Used excluisively to measure the elongation of webbing material. United\'s Webbing extensometer can accommodate a measuring range of 1 to 2 inches, and a gage length of 8 to 10 inches.

Using a unique laser scanning approach developed by United Calibration Corporation, the United Laser Extensometer permits accurate non-contact extension measurement from the start of the test through sample failure without test interruption. Designed to provide accurate extension measurements from less than 1% to greater than 1000% strain, this versatile optical scanning device performs well for sample testing with an environmental chamber at elevated or even very low test temperatures, as well as at normal temperatures and environments.

Using the principles of laser diffraction, this unique system is designed to accurately measure the cross section of carbon and other opaque fibers and filaments in the diameter range of five to fifty microns.

United's Model DIG-5000 Smart Digital is a precision data acquisition system. It is designed for ease of use while providing the operator with a variety of options usually available only with computer-controlled test machines.

United's Load Cells are designed to precisely measure the amount of force (load) applied to the specimen being tested. Available in single or dual bridge, United load cells offer the flexibility of using two readouts simultaneously, if desired. Constructed to meet ASTM E-4 requirements.
