Today’s precision digital scales, also referred to as digital balances, perform a broad range of weighing-related functions in R&D, quality control, and similar applications where accuracy and precision are key criteria to meeting government, trade association, and industry-promulgated standards. For purposes of discussion this post focuses on weighing equipment used in comparatively protected environments vs. scales found on manufacturing floors, shipping and receiving departments. Let us hasten to add, however, that the need for precision and accuracy is important for any application, and equipment is available to meet required standards regardless of where scales are employed.
Precision and Accuracy Defined
Certain of our posts discussing precision digital scales and analytical balances harp on an important difference between precision and accuracy as selection criteria. Allow us to cite an example: A $5,000 wristwatch may be precise, but if the hands are set wrong it does not show the accurate time. More … Read the rest
