Old-style Weighing Scale
These old balance-type scales are the weighing scales I used to see (and use at my mom's small grocery store) when I was a child. They are still very much in use in most traditional markets here, but I don't see them much anywhere else. Modern markets and supermarkets prefer to use electronic strain gauge scales because they are considered more accurate although, scientifically speaking, balance-type scales are actually more accurate because they are not affected by local gravitational force and/or temperature which can affect the spring type of scale, of which strain gauce scales are part. The cylindrical brass in the foreground of the picture, by the way, is called the masses. Here, their measurement is marked in kilogram scales: half an ounce (50 grams), an ounce (100 grams), a quarter of a kilogram (250 grams), a half a kilogram (500 grams), and a kilogram (1000 grams).
