They provide a very accurate electrical signal, strictly proportional to the strain of the specimen submitted to load application, for determining the Elastic Modulus and strength characteristics as alternative to the Compresso meter-Extensometers which can be used only on samples  with min dia.75mm and min height 160mm. They can be applied to the specimen surface by a special Adhesive-Catalyst agent and other accessories all included in the Strain gauge application kit.

Ltekonline are the manufacturers of Strain Gauges used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Rock Mechanics Testing Equipment for Engineering Teaching Lab in Universities
