Closed Case Form Electroscope is enclosed, preventing air currents from affecting the deflection of the leaves.

• Booklet of Six Leaves
• Instructions
• Gold and Aluminum Leaf Construction
• Enclosed Electroscope
• Leaves Pivot when Charged

Leaves are a combination of gold and aluminum developed to provide strength without sacrificing sensitivity. Each leaf is suspended from two small hooks for simple installation, and the leaves pivot, rather than bend, when charged.

The metal case eliminates deflections caused by charges residing on glass walls. An insulating plastic sleeve holds the leaf-support rod in place. Front and rear sides of the box are made of a 10 cm square glass pane to allow visibility and shadow projection.
