The analytical balance is a laboratory equipment, also known as a scale, designed to measure the quantities of masses to be studied with a high level of precision. This type of balance is one of the most used measurement tools in the laboratory, which depends fundamentally on all analytical results.
In this sense, they must have calibration adjustments necessary to repair gravitational differences. They use an electromagnet, called an electromagnetic force restoration sensor, to form the force that counteracts the sample to be measured, and gives the result, calculating the force needed to level the balance.
