Key Features

Potentiometer Slide Wire Type Alum Base bosshead The scale inside allows forThe Potentiometer Slide Wire Type Alum Base is an effective and precise instrument for measuring small voltages in electric circuits. When used with a Galvanometer, a change over switch, a 4V or 6V battery, and a Standard Cell or Voltage Reference, it is a key tool for teaching about electricity. Both models have a construction that includes an aluminum channel base to prevent warping and cracking compared to wood. A metric rule is placed below two
