Guardelli Magnetic Thickness Caliper

This unique tool, based on laws of magnetic fields, enables you to measure the precise thickness of wooden or any other non-ferromagnetic material where standard measuring tools can not be used. The small 8mm diameter counter-magnet is inserted inside the instrument or placed on the opposite side of any measured surface.

• Quick, effective and easy to use, with no risk of damaging even the most sensitive varnishes/surfaces
• Comes in a protective leather case
• Magnet with rounded surface for high precision spot measurements also on concave surfaces

• Version A: 0.8mm-6mm
• Version B: 1.8mm-10mm

Guardelli magnetic calipers can measure not only in vertical position, but in any position provided the tube is perpendicular to the measured surface.
