PCE Instruments COM 20 Material Tester for Non-Ferrous Metals

Model # COM 20

PCE-COM 20 is a portable handheld non-destructive material tester for non-ferrous metals. This non-destructive testing (NDT) device uses eddy current to determine the electrical conductivity of non-ferrous metals such as aluminum and copper.
Featuring an operating frequency of 60 kHz, the conductivity meter has a large measuring range of 0.51 … 112% IACS with an accuracy of +/- 0.5% at 20°C / 68°F.
Thanks to a resolution of up to 0.01% IACS, automatic temperature compensation (ATC), and lift-off compensation (up to 500 μm), the device ensures quick, easy, accurate, and reproducible measurements of coated or corroded pieces during changing ambient conditions.

Measurement of the electrical conductivity of non-ferrous metals, such as aluminum, copper, titanium, magnesium, or bronze, is necessary for applications involving electrical conductors and the characterization of alloys.
Typical application areas are the assessment of strength differences in heat-treated or hardened materials, the authenticity testing of coin alloys, the verification of alloy inhomogeneities in critical components, and the sorting of materials.
The conductivity meter is powered by an internal battery that can be charged via the interface on the bottom of the unit. In addition to the connection for the charging adapter, there is a USB interface allowing for the transfer of measurement data to a PC for more detailed analysis.
