ZJ Strain Controlled Direct Shear Apparatus (Two speed Three speed)
ZJ Series Strain controlled Direct Shear Apparatus 

Application:
ZJ Series Direct Shear Apparatus is a kind of strain controlled direct shear apparatus used to test resisting shear strength of soil specimen, it usually adopts four specimens under the different vertical pressure exerted on the specimens to obtain shear stress when the specimen is destroyed. According to Coulomb’ s law to confirm the resisting shear strength coefficient, angle of internal friction and coagulable force of the soil.
