Portable Conductivity Meter has been developed to facilitate easy determination of conductivity of nonferrous metals based on eddy current principle. This Instrument uses a probe which when placed on the surface of metal indicates conductivity on a linear scale panel meter. The instrument can be used to measure stressed conditions if they can be related to the electrical conductivity of the specimen. Whilst the accuracy claimed is 2%however, for high conductivity samples an accuracy of better than 1%is easily obtained. The users can also, if desired, use their own sample of known conductivity in the region of interest to enhance the accuracy.The instrument is supplied in a rugged carrying case which gives complete protection and has separate pocket for probe.
