Metal Mechanical Extensometer, Packaging Type : Silver Or Metallic

We are offering mechanical extensometer , we are counted amongst one of the major manufacturers and exporters of mechanical extensometer. Our mechanical extensometer is designed to measure the elongation of test specimen under load, in order to have its mechanical properties.  
further, the clients can avail our quality-tested mechanical extensometer at very moderate prices in the markets. 
construction & application
this consists of two long knife edges at top. Two dial indicators and lower knife edges to actuate the dials. The bars are pressed against the specimen by means of clamp. So that the knife edges bite the specimen to avoid any slip. The upper edges are adjustable to provide different gauge lengths for measurement. As deformation takes place the lower knife edges transfer the movement to the dial gauges and the deformation of specimen is shown on dials. So that the change in length of specimen by 1100 mm, equals to one division of the graduation on dial.
