Features of American Epsilon extensometer:

Universal axial extensometer, suitable for measuring small deformation in axial tension, compression and cycle test;

Gauge range: 10-50 mm;

Deformation range: 5%-100% of gauge length;

The extensometer can be used to measure the deformation of materials such as metals, plastics, composites and ceramics;

It is suitable for tensile and compression tests, and can also be used for deformation measurement in cyclic tests;

You can use the quick clamping device to install the extensometer to the sample with one hand in a few seconds, or use a spring or rubber band to install the extensometer to the sample.

There is no need to remove the extensometer when the sample breaks;

Full bridge, 350 ohm strain design, compatible with most testing machines;

Two-way over-travel mechanical stop;

Meet the existing ASTM B-1 level and ISO9513 level 0.5 accuracy requirements;

Hard tool steel blades are easy to replace, and a set of spare blades is provided with it;

The extensometer can be selected according to the temperature range, and the applicable temperature range is -265℃－+175℃;

A high-grade foam pad carrying case is provided;

The arm and partition are easy to maintain, and the gauge length can be changed according to the test requirements;

It adopts double-bending structure design, which is sturdy and durable, insensitive to vibration, and suitable for high frequency test;
