Digital and precision scales belong to the inventions of the digital age. A digital scale is a weighing device in which the weight or mass of a material is displayed in digital numbers. Today, precision balances most commonly can be found in the pharmaceutical industry and chemical companies.
Having said that, there are also other places where precision balances are used, e.g. educational facilities. Technology found in the recent weights enables automatic calibration on any surface. This gives exact results every single time. In the older types of scales the user had to calibrate the scale every time before using it, which affected the comfort of use. With the implementation of auto calibration that problem has been done away with. The scales now calibrate on their own, making sure you get the best reading every time.
