The SIGMATEST 2.070 is a portable eddy current instrument which measures the electrical conductivity of non-ferromagnetic metals based on the complex impedance of the measuring probe.

It determines physical and technical material properties. Typical applications include controlling the quality of manufactured products, testing material combinations, and sorting metals, alloys, and scrap metal. The unit is also used for the maintenance of aircrafts, determining heat damage, and in-process controls during production and processing in the metallurgy sector. It features five different excitation frequencies and an extremely high measuring accuracy. The unit retains this high level of accuracy even at a high frequency of 960 kHz, making it possible to measure very thin workpieces with great precision. The measuring instrument is able to automatically standardize the measured value of the electrical conductivity to 20°C due to an integrated temperature compensation. The measurement quality meets Boeings (BAC 5651) and Airbus standards.
