Abstract
A portable seam resistance measuring apparatus having a housing with one or more flat exterior surfaces, a number of apertures, an indicator at the midpoint of the flat surface, two or more current injection probes, two or more voltage injection probes, a mechanical bias on the probes, a number of connectors, an electrical current through two probes and voltage measurement through two probes is disclosed. The device is used to measure the voltage drop across the seam of a wall enabling the resistance of the seam to be calculated.
