Improvements in the construction of ball scales, which consist essentially of combining with the scale or reading limb of the scale, a sector of circle revolving concentrically to the sphere and independently of the needle and in whose peripheral edge presents corresponding divisions with those of the main scale and which can be made to coincide with any group of them by rotation of the sector, for the purpose of which said sector is integral with an axis mounted through the center of the protective glass of the sphere, said axis being balanced for the stability of the various positions of the sector, by means of a counterweight that is fixed to the end of an arm that is part of the sector and diametrically opposite to its reading scale.
