Model: GWB-200JA
Application:
GWB-200JA Calibration instrument for extensometer is a sort of pure mechanical instrument to determine the displacement, deformation, or extension. It has high precision. According to JJG762-92 V.R. of extensometer, 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.
