Clip-on extensometer

WANCE designs and manufactures clip-on strain gauge type of extensometer which provides cost effective solution for extension measurement.

It includes different gauge length and strain range options to suit a wide range of specimen characteristics.  All extensometers comply with both the ASTM E 83 and IS0 9513 standards. Calibration certificates are supplied, showing the individual performance of each unit at its factory calibration.
