Expensive ones differ in that there are two disks in the design of the scales, between which aspecific capacitor. Under the influence of gravity, the distance between them changes, from which its capacity decreases. The electronic scoreboard converts this pressure into weight and displays it on the screen in familiar numbers.
There are models with a different principle of operation, in which a voltage sensor acts as part of the measuring element, an electric current passes through it. At the time of weighing an object or product, the device is able to change the resistance and power of the passing charge. After converting to kilograms and grams, the result is displayed on a familiar scoreboard. In such models there are no mechanical elements at all.
Desktop scales may differ in terms of power supply. Some are powered by solar panels, others have galvanic cells, and others are power supplies.

Laboratory scales
Models have increased accuracy, designed for weighing small suspensions in laboratories of research institutes and industrial enterprises. Classified into:
- Precision - with weighing accuracy up to 0.1 mg;
- Analytical - up to 1 year
Equipped with many extra features and various calibrations.
Medical scales
Desk scales are used in pediatrics for weighing babies. They areable to quickly and accurately determine the body weight of the child.

Such devices are often tested and have a certificate of conformity, in accordance with the legislation of the Russian Federation.
Advantages and disadvantages of electronic scales
Like any other apparatus, scales have their positive aspects:
- High measurement accuracy.
- Modern models are able to show the result in different units.
- They move to the starting position, while they can maintain the previous weight.
- Have a high measurement limit.
- Wide selection of model mesh.
- Small size.
- Easy to operate.
- When inactive for a long time, they are able to switch to standby mode without consuming power.
Don't forget about the disadvantages:
- High cost.
