FIELD: measurement equipment.
SUBSTANCE: instrument comprises a platform hingedly fixed on a stand, a scale and a traction device. On the platform there is a plate fixed from the investigated material with longitudinal slots of semicircular shape with radius (R), which is larger than the maximum size (rmax) of curvature of the cross section contour of particles of the investigated loose material, but with smaller diameter (2R) of their length (1).
EFFECT: reduced labour intensity of measurements.
