Pinhole Tester (for Aluminum Foil)

Pinhole Tester for Aluminum Foil (also known as the Light Box), is an equipment which can help detect pin holes in aluminum foils used in pharmaceutical packaging.

Pinholes are micro leaks in the foil surface which can reduce the shelf life or stability of the product they are used to protect.

This equipment can be used only on opaque materials.
