FIELD: physics.

SUBSTANCE: device consists of portable housing in which there is a force-measuring sensor, a digital display and an electric measuring circuit, which is equipped with a peak detector, and a berry gripping device which is mechanically connected to the force-measuring sensor through a rod-shaped force distributor, and a device for controlling the gripping device. The gripping device is in form of pivotally connected fixed and spring-loaded movable cup-shaped gripping jaws which grip the berry from the side opposite the side where it is attached to the fruitstalk. The end of the fixed jaw is attached to the rod-shaped force distributor, and the end of the movable jaw, in order to facilitate opening and closing of jaws, is kinematically connected to the device for controlling the gripping device.
