  • Separation between signals from defects and noise
  • Small untested zones close to the tank wall and to plate welds
  • Testing under installations and heating pipes down to 130 mm space
  • Testing of plates up to 25 mm thickness
  • High testing speed
  • No coupling fluid is necessary
  • Testing through non-conductive coatings up to 10 mm thickness
  • Comprehensive result documentation in 2D-colour scan inclusive single plate report, feature list and repair plate input

Result Documentation

The result documentation consists of a coloured tank floor map, single plate reports and if required feature list , repair plate map and repair plate list. In the tank floor map and single plate reports wall thickness reductions will be shown in a 2D-scan image, where the defect depth corresponds to a defined colour.
