• Access to a wide range of geometries using TSC's range of active topside probes.
• Reduced component cleaning requirements with no need to clean to bare metal.
• Capable of inspection through thin metallic coatings, or through non-conducting coatings up to 5mm thick.

• WindowsTM based software for ease of operation and compatibility with other Windows applications.

Comparison

The Model U21 Crack Microgauge is in use around the world for subsea weld inspection. The Model U31 provides all the functionality of the Model U21 but in a significantly smaller package.

The U31 weighs only 4.3Kg in water and has a standard operational depth of 350 metres. In addition TSC offer a specialised system capable of operating at depths up to 2 kilometres.
