The Electromagnetic Thickness Tool (EMT05) can measure damages and corrosion areas of single-layer pipe strings,or measure double-layer pipe strings simultaneously (such as oil pipe string, production pipe string or double-layer production pipe strings), provide quantifiable average wall thickness information on the circumferential direction, draw schematic diagram or provide data table accurate to the millimetre; at the same time, be able to determine the location of the damaged sector of the inner pipe string. Features: pipe thickness measurement,through tubing measurement of casing pipe, high sensitive thermometer, axial and horizontal damage detecting of steel pipe.
