Mass meters are devices used to measure the mass of an object. They operate based on various principles, such as the force of gravity or the use of electromagnetic fields. Common types include balance scales and load cells, which provide accurate readings for different applications, from laboratory experiments to industrial processes. These instruments are essential in many fields, including science, engineering, and manufacturing. By providing precise mass measurements, mass meters help ensure quality control, facilitate research, and support various calculations in both commercial and academic settings.
