Mechanical scales are a great solution for weighing in areas with no power source or areas requiring intrinsically safe equipment. The inherit benefits of a mechanical scale are the long life with minimal maintenance fees. Mechanical scales work by measuring a deflection and the deflection is converted into weight. Mechanical scales also remain precise, have minimal moving parts, and are easy to calibrate. If you would like some help figuring out which scale is best for your application, let us know.
