The direct shear apparatus we offer is designed as per is: 2720 (part-viii), astm d 3080 standards. Direct shear apparatus is extensively used for determining the direct shear strength of soils on specimen size 60mm x 60mm x 25mm. The direct shear apparatus we manufacture is electrically operated to give a 6 rates of strain of 1.25, 0.25, 0.05, 0.01, 0.002 & 0.0004mm/min and is suitable for 230v a.C.

Specifications: the apparatus comprises of the following:
