Magna - Mike 8500 Precision Thickness Gage

 

The Magna-Mike Model 8500 is a handheld, easy-to-use thickness gage that uses a magnetic method to make fast, accurate and repeatable measurements of nonferrous materials. Measurements are made when a magnetic probe is held on one side of the test material and a small steel target ball is placed on the opposite side. The probe’s Hall Effect sensor measures the distance between the probe tip and ball, resulting in a digital thickness reading.

FEATURES & BENEFITS

  • Minimum Mode continually displays the lowest thickness readings

  • Handheld and lightweight (2.1 lb / 0.95 kg)

  • Extensive file-based datalogger with RS-232 serial communication port

  • Few keys for simple operation

  • Backlit liquid crystal display with large numerals

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 in (0.79 mm). The display simultaneously shows the thickness measurement and the minimum measurement reading. The Magna-Mike is considered the industry standard in plastic packaging, but other proven applications include glass containers, composites and non-ferrous metals.
