Magna-Mike 8600

The Magna-Mike is a Hall Effect thickness gage that uses a magnetic probe to perform accurate measurements on nonferrous and thin materials such as plastic bottles.


Magna-Mike 8600

The Magna-Mike® 8600 is a portable thickness gage that uses a simple 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 or scanned on one side of the test material and a small target ball (or disk or wire) is placed on the opposite side or dropped inside a container. The probe's Hall Effect sensor measures the distance between the probe tip and target ball. The measurements are instantly displayed on the large color thickness display as an easy-to-read digital thickness reading.

Plastic and Glass Bottles and Packaging

Plastic and Glass Bottles and Packaging

In applications such as plastic containers, simply drop the small target ball inside the container. The magnetic probe held on the outside of the container attracts the target ball. When scanning 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.

Automotive Tear Seams

Automotive Tear Seams

The standard probe along with one of the two target disks and a replaceable chisel wear cap makes the Magna-Mike 8600 ideally suited for most automotive tear seam applications where measurements need to made in a thin channel or groove.

Aerospace and Other Applications

The Magna-Mike has been successfully integrated into quality control programs to measure aerospace parts made of composites and nonferrous materials. The wire targets can be inserted into cooling holes in turbine blades and the larger magnetic target balls can be used to measure jet engine parts up to 25.4 mm (1.00 in.) thick.
