A balance beam type scale which is particularly adapted for educational purposes, i.e. for use by grammar school children. The components of the scale are easily assembled. Also, the scale is so constructed and arranged as to permit the weighing of a solid article, granulated materials or a liquid. Although the scale is ruggedly constructed for use by children, it includes features which have heretofore only been found in more expensive scales, for example a check lever. |
