Integrated External Detection Machine

Integrated external detection equipment integrates various external detection technologies, including pipeline electromagnetic positioning, AC voltage gradient, DC voltage gradient, sonar detection, close interval potential detection, GPS coordinate mapping and other detection technologies, to achieve continuous collection of multiple detection data at the same time and at the same detection point, and correlation through high-precision GPS coordinates. Finally, the analysis software combined with the evaluation method stipulated in the domestic standard objectively analyzed and evaluated the test data.
