Centurion NDT FM-140XL Digital Conductivity Meter


The Centurion NDT Model FM-140XL Conductivity Meter makes conductivity testing simple and worry free for most non-ferrous metal testing. Portable, yet ruggedly designed, it instantly generates readings with a bright, direct digital display, in percent IACS (International Annealed Copper Standard). To prolong battery life, readings only display when probe and testing surfaces meet.

The FM-140XL delivers precision accuracy to +/-.5% of the readings at 20° C. Included is a RS-232 port, which allows the user to download information to computers, micro-controllers or other peripherals. The FM-140XL is housed in a compact, lightweight and shock resistant case, for long life and durability. Placing the probe against the testing surface generates a direct conductivity reading in large brilliant LED lights.


The FM-140XL Conductivity Meter is useful for sorting a wide variety of non-ferrous metals and alloys, as well as for measuring changes in physical properties reflecting conductivity. Such changes include hardening, annealing, variations in alloy, heat treating corrosion and/or aging.

Its rechargeable Ni-Cad batteries provide up to 10 hours of continuous operation from one charge. A lift-off compensation circuit easily handles rough surfaces and compensates for probe wobble. Two test samples are mounted atop of the unit for easy set up.


Accuracy: +/- 0.5% at 20°C.
