The Olympus (Panametrics) Magna-Mike 8500 Precision Thickness Gauge is a handheld thickness gage that utilizes a magnetic method to make reliable and repeatable measurements on nonferrous materials. Operation of the Magna-Mike is very simple. Measurements are made when its magnetic probe is held on one side of the test material and a small steel target ball is placed on the opposite side. A Hall-effect sensor built in the probe measures the distance between the probe tip and target ball. The measurement is instantly displayed as an easy-to-read digital thickness reading.

In applications such as plastic containers, the operator simply drops the small target ball inside the container. The magnetic probe held on the outsider of the container attracts the target ball. When the operator scans the probe along the surface or critical corners, the small steel target ball will follow. In the Minimum Mode feature, the gage continually displays both the actual thickness and the lowest thickness reading.

The Panametrics 8500 Thickness Gauge is the ideal instrument for measuring difficult shapes and sizes. Nondestructive measurement capabilities allow for pinpoint thickness readings in tight corners and grooves down to a radius of 1/32". The Magna-Mike has been successfully integrated into quality control programs for glass and aluminum containers, aerospace composite parts, medical packaging, automotive panels, airbag tear seams, and other parts made from nonferrous materials.
