Specifications: 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 a electrically which operates a worm gear arrangement during the upper end of a calibrated torsion spring. Vane dia., rod dia., vane size & vane height as per IS specifications. The Vane Shaft is attached through the hollow upper shaft to a resettable pointer, which indicates the angle of torque on a dial graduated in degrees. The dial reading multiplied by spring factor gives the torque. A container for soil sample is also supplied, and a sampling tube of 38 mm I.D. & 150 mm long can also be used as container. Supplied with set of four springs, one each of approx. 2 kg.cm., 4 kg.cm., 6 kg.cm., and 8 kg.cm. Complete as above in a wooden carrying case.Rate of rotation is 1/60 r.p.m. Suitable for operation on 230 volts, single phase, 50 cycles, A.C.supply.
