Economical Foil Electroscope

  Enclosed in an acrylic box with a plastic base, this type of electroscope is economical as well as compatible with other apparatuses that are used to carry out other electrostatic experiments. The single-piece construction of the box greatly improves the prevention of air flow from interfering with the deflection of the electrostatic leaves. The use of a clear acrylic design allows for observation of the foil leaves from all directions. The ability to ground the box can help with reducing deflections that are caused by residual charges within the case. A slightly elevated black base snaps securely onto the acrylic electroscope box, providing a solid and uniform surface for the unit.

The box itself measures 8x5x14.5 (LxWxH), and the base measures 10.6×7.1×1.5 (LxWxH).
