A double-pan balance scale
A balance scale is an instrument used to measure the weight of objects by comparing their weights to a set of known weights.
A double-pan balance is a scale which has 2 pans that are balanced against each other. The scale functions like a see-saw, with each of the 2 pans attached to a beam over a centered pivot point.

1）Usage

The object to be weighed is placed on 1 pan. The other pan is gradually loaded with small weights until the scale balances, as shown by a measurement gauge reading "0." The weights are added up to get the weight of the target object.

2）Benefits

The weights of 2 different objects can be immediately compared using a double-pan balance. An object is placed in each pan, and the heavier pan will drop while the lighter one rises. This will show which object is heavier, but it will not show the actual weights of the 2 objects.

3）Other Uses

A double-pan balance can also be used to determine how much of a substance makes up a specified weight. For example, if you wanted to measure 10 grams of sand, you could load 1 pan with a 10-gram weight, and then place sand in the other pan until it balances.
