Introduction:
GWB-200JA calibration instrument for extensometer is a sort of pure mechanical instrument to determine the displacement, deformation or extension. It is specially used for the calibration of various extensometers, and also widely used for the verification of displacement sensors and dial gauges (reading in 0.01mm and 0.001mm).This instrument can custom-tailor and lengthen the gauge length but with changeless performance and precision
