Centurion FM-140XL Digital Eddy Current Conductivity Meter

Centurion NDT's 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 digits. The front panel features a sorting gate, go/no-go, red or green LED display.


Its rechargeable Ni-Cad batteries provide up to ten 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.


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


Accuracy: +/- 0.5% at 20°C. 
 RS-232: Downloads data into the user's computer, micro-controller or other peripheral.
 Resolution: 0.1/IACS for any reading
