Lizard NDE Ltd are a family owned, UK based company and are the sole providers of the LIZARD AC Field Measurement non-destructive testing technology Staffed by a dedicated team of professionals with many years of NDT experience, both high level laboratory and site, on and off shore.

Advanced AC Field Measurement Technology


  • Lizard's unique Field Gradient technology and LIZARD software provides Field Gradient Imaging, Electromagnetic Array, Alternating Current Field Measurement and standard Eddy Current data information from each sensor element in a single scan pass whether site or laboratory based.

  • Regarded as an 'Electromagnetic toolbox', the Lizard technology is the only AC Field Measurement device to enable a mix of electromagnetic inspection techniques in a single unit, with variable frequency options via software to enable a wide variety of metallurgical interrogations to be performed with a single device.

  • Reliable, rapid inspection through either conductive (zinc, flame sprayed aluminium, etc.) or non-conductive (paint, composites, etc.) coatings of structures or piece parts with repeatable results for true defect monitoring with real-time and archived ‘Lift Off’ data information per channel (probe coupling information, an absolutely vital component of auditable inspection and vital assistance to robotically deployed inspection programs).

  • Inspect, detect, analyse and monitor surface breaking defects with true length and depth output across the entire defect profile without the requirement to re-scan. Size defects at leisure whether on site or at later review stage

  • Independent Length and Depth sizing using Lizard's defect sizing algorithms, therefore no dependence on length measurement to identify depth of flaws

  • Unaffected by residual magnetism.

  • License free software package, no subscription or usage costs for Lizard users with replacement software available for an immediate no cost download

  • LIZARD software operates under a Windows environment with advanced features utilizing simple software sliders for rapid data manipulation and operator ease.

  • Advanced phase alteration and positioning using the Lizard Adjustments menu, enabling sensitivity enhancement and Fe or Non-Fe set up using the same devices.

  • High Probability of Detection with significantly low False Calls, the inclusion of Classic Eddy Current data per channel provides for lower false calls than any other AC Field Measurement system on the market since the user has an additional data stream unavailable to other similar technology types.

  • LIZARD probe types are available as topside or subsea variants (diver or ROV deployed) with the ability to utilise a topside to subsea cable type for the immediate use of the Lizard technology subsea with a topside Lizard M8 XL.

  • Dedicated sizing mode for rapid and detailed defect analysis, length and signal depth information is provided from a single scan pass without the requirement to perform physical measurements on site. Size defect data at anytime, anywhere and at any point along the flaw's profile.

    • These results would not have been achieved if it weren’t for the exceptional help from Lizard" - Offshore Subsea Robotics Engineer
