It is essential to measure the elongation of test specimen under load to have it's mechanical properties.FIE Extensometer, Model EM-1 is intended to serve the above purpose.
This consists of two long knife edges at top, two dial indicators and lower knife edges to actuate the dials.The bards 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 1/100mm, equals to one division of the graduation on dial.
Due to constant R & D, Specifications and Features are subject to change without notice. The Dimensions given above are approximate.
