Paper scale
Pic PY 6

Nice quadrant pendulum scale for testing the weight of paper. The scale is made by F.R.Poller and is fixed on a  three leg stand. A 5x10 or 10x10 cm sample of paper was suspended from the fine wire hook. The estimated weight of a qm of the paper was indicated by the pointer. The complete scale is 19" tall and 13,5" wide.
