ABSTRACT:
The higher the reading of relative density, liquid weight per unit volume, of pieces of produce such as fruits, the juicier the piece of produce is. By comparing a number of pieces of produce of the same type and species and ranking them, the juiciest pieces of produce may be easily selected and purchased by a shopper. An arrangement of linkages and a sliding spring element creates a device with two inputs, one input being proportional to the volume of the produce based on a representative diameter, and the other input being an approximation of the weight of the produce based on the deflection of a spring. The two inputs are mechanically combined to create one output indicative of density, and thus juiciness, and a pointer is employed whose deflection is proportional to the quotient of the weight and volumetric inputs of each piece of produce tested by the shopper.
