Corrosion Mapping Scanner

The MapMan – OH scanner is a two-axis manual X-Y scanner designed for use with the Olympus HydroFORM probe. MapMan is fully encoded on both axis and has the ability to inspect pipes from 4” OD through to flat on any material.

The unique free-moving arm allows for the inspection up to a maximum stroke of 550mm. The scanner has sets of magnetic wheels which give the scanner rigidity and stability when performing an inspection. This enables data to be collected in a simple, fast, and cost-efficient manner by eliminating the need to re-scan areas.

The scanner design incorporates an overlap feature that can guarantee 100% coverage of the component. An additional feature of the scanner allows the operator to use it on non-ferritic material simply by removing the magnetic wheels and replacing them with a belt at either end of the arm, available from 4″ OD up to 48″ OD.

The MapMan is designed to operate with any multi-channel flaw detection system.
