the accuracy is generally 1.1g or 1.2g ..

accuracy refers to the minimum value that can be called, also called inductance; There is a weighing scale on the balance, with a wandering code on it. The minimum scale value on the scale generally represents 1.1 or 1.2g, and the minimum scale is 1.1.

In the process of scientific experiments, it is sometimes necessary to weigh some solid substances, such as salt, baking soda, etc. At this time, a weighing tool-tray balance is needed.

The pallet balance is made by using the principle that the forces acting on the equal arm are equal when the lever is balanced. It is mainly composed of a walking code, a scale, a balance nut, a bottom plate, a dividing plate, a cross beam pointer, and a heavy vertical line.

Extended information:

In the middle of the 7th century, the French mathematician Laubel Barr invented the tray balance, which is more convenient than the hanging balance used by the ancient Egyptians. At that time, the popularity of balance instruments even promoted the development of French chemistry at that time.

subsequently, a precise pallet balance was born in Britain at the end of 18. A steel knife edge was embedded in the center of the beam, and then it was placed in an agate plate, which greatly improved the precision and sensitivity.

in the 1921s, a British instrument designer invented an analytical balance with higher precision, which made the balance enter the ranks of precision weighing instruments. Later, the high sensitivity made analytical balance become a common weighing instrument in chemical laboratories in various countries.
