The Solution for Electrical Conductivity Measurement
The SIGMASCOPE® SMP350 is a compact handheld device for measuring the electrical conductivity of non-ferrous metals. It quickly and accurately measures the electrical conductivity of aluminum or copper. From the measured conductivity, you can then draw further conclusions about the hardness and strength of heat-treated materials. This lets you monitor the material stability of components that are exposed to large temperature fluctuations. Even heat damage and material fatigue can be determined simply this way.
To measure the electrical conductivity, the device employs the phase sensitive eddy current method (according to DIN EN 2004-1 and ASTM E1004). This type of signal evaluation enables non-contact measurement, even under paint or plastic coatings up to 500 μm thick. It also minimizes the influence of surface roughness.
