Balanced Beam Coin Adapter

The Balanced Beam Coin Adapter is a device originally developed as a quality control tool to determine the ease of removal of special "scratch-off" coatings applied to lottery tickets. It has been found to be equally useful for testing the properties of paint, coatings and other materials including paper and paper products. The coin adapter is a rod attachment that can hold a coin in its chuck for use as a scraping tool. The adapter clamp can accommodate a coin (Nickel, Dime, Euro, etc.) and allows the user to test the resistance of their coatings to scratching and marring from the milled edge of the coin.

In adhesion testing, sometimes the edge of a Hoffman type pencil may be too sharp and the loop or stylus may not be sharp enough. In this case, the edge of a coin can have only the right edge. Not only will a coin provide a different type of edge, but the adapter also allows the user to insert virtually any type of test coupon desired (such as a thin wafer), as long as it is approximately the same thickness as a coin. When using the coin adapter, follow the normal operating procedure.
