Magna-Mike 8600 from Olympus

Accurate measurement of the thickness of thin-walled items such as blow-moulded plastic bottles is now easier following the release of the Magna-Mike® 8600 Hall Effect thickness gauge from Olympus NDT.

This unique instrument is a portable thickness gauge that utilises a magnetic method to make reliable thickness measurements on non-ferrous materials.

It is a versatile tool, which can be used in a wide range of applications including measurements of thermo-formed plastic trays, extruded tubing, and automotive tear seams.

The Magna-Mike 8600 can also be used on glass and composites, as well as any non-ferrous metals, such as aluminium, brass, copper and titanium, with a thickness range from 0.001-25.4mm.

Taking a measurement with the Magna- Mike 8600 is a simple procedure. The magnetic probe is held or scanned on one side of the test material while a small target ball 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 the target ball, which is instantly displayed as an easy-to-read digital thickness reading. Material properties do not affect the instrument’s accuracy.

The Magna-Mike 8600 has both straight and angled magnetic probes with replaceable wear caps to increase durability and reduce replacement costs. An expanded assortment of magnetic and non-magnetic steel target balls, discs and wire targets makes the Magna-Mike 8600 the ideal instrument for applications with complex geometry where ultrasonic thickness measurements are difficult or impossible.

Non-destructive measurement capabilities allow for pinpoint thickness readings in tight corners and grooves.

The instrument also boasts powerful standard thickness measurement features such as minimum and maximum scan and a strip chart view feature. The colour LCD display with full VGA resolution provides superior readability and a simple keypad makes it easy to access important functions. USB, RS-232, and VGA outputs are provided for connection to external displays.

The Magna-Mike 8600’s internal data-logger provides on-board storage of thickness data of more than 475,000 thickness readings in various fi le formats. The unit also features a MicroSDcard slot for additional storage and data transfer. The instrument can export data to the MicroSD card in CSV (Comma Separated Values) or text formats that can be copied or pasted into almost any Windows program.

The included WinXL interface program allows the Magna-Mike 8600 to send thickness readings directly to an Excel spreadsheet.
