Direct Current Voltage Gradient Survey

A Direct Current Voltage Gradient (DCVG) survey is a non-intrusive, above ground survey technique used for locating and assessing corrosion or damage on buried pipeline or cable. Prior to performing costly excavations to perform pipeline or cable repairs, conduct a survey using this mobile app to identify the exact coordinates of problematic locations. Collect GPS locations, percent intensity (current) of resistance (%IR), and other DCVG measurements using this mobile survey and customize the form to fulfill specific needs of your project.
