86681 GWB-200J 8726

GWB-200J Calibration instrument for extensometer is a sort of pure mechanical instrument to determine the displacement. It has high precision. According to JJG762-92 V.R. of extensometer and JJF1096-2002 C.S. for Calibration instrument for 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.
