This is a triple beam scale (or balance) which I purchased at a local store. I has gradations down to 1/10th of a gram. It comes with optional attachment weights that bring the capacity up from 610 grams to 2610 grams.
Capacity (maximum it can measure): 2610 grams
Examples of where I've used the scale
One of the first uses was to measure the weight change in a non-conventional propulsion experiment involving something called a lifter.
But I've also used it for a more conventional purpose such as weighing barium titanate and epoxy for making a capacitor.
