Used and good working condition Panametrics NDT Olympus Magna Mike 8500 Hall Effect Thickness Gauge available for sale, including Panametrics NDT Makna-Mike 801PR Probe, Probe cable, Battery and Charger.

Condition: Used

The Panametrics Magna-Mike 8500 is a handheld thickness gage that uses magnetism to perform reliable and repeatable measurements on nonferrous materials. Using the Magna-Mike 8500 is very simple. Measurements are performed by holding the gage's magnetic probe to one surface of the test material and placing a small steel target ball on the opposite surface. A Hall-effect sensor built into the probe measures the distance between the probe tip and target ball. Measurements are instantly displayed as easy-to-read digital readings.

Plastic Bottles
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.

Other Applications
The Magna-Mike 8500 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.
