Consists of a torque head adjustable in height by means of a lead screw rotated by a drive wheel to enable the vane to be lowered into the specimen. Rotation of the vane is by means of an electrically operated rate of rotation is 1/60 R.P.M. It operates a worm gear arrangement turning the upper end of a calibration torsion spring, vane dia, rod dia, vane size vane height are as per IS specifications. The vane shaft is attached through the hollow upper shaft to are settable pointer, which indicates the angle indicates the angle of torque on a dial graduated in degree the dial reading multiplied by spring factor gives the torque a container for soil sample is also supplied a sampling tube of 38mm. i.d. 150mm long can also be used as container. Supplied with set of four springs, one each of approx. 2kgs/cm2, 4kgs/cm2, 6 kgs/cm2 8kgs/cm2 complete as above in a wooden carrying case.
