A platform balance is an instrument to weigh things.

From (see link to the left):

The platform balance is a form of equal-arm balance in which two

flat platforms are attached to the top side of the beam, one at

each end. Such a balance has a rider, or weight, mounted on a bar

that has a calibrated scale, is parallel to the beam, and connects

the supports of the two platforms. This rider is moved along the

bar, its edge marking decimal fractions of the unit weight.

See the Related Questions to the left for more information
