ETher WeldCheck Series Eddy Current Flaw Detectors

ETher WeldCheck Series Eddy Current Flaw Detectors

Superior Performance Weld Inspection

Superior Performance Weld Inspection

Both the WeldCheck+ and WeldCheck 2 can perform a great many eddy current inspection tasks due to their superior performance, including weld inspection, surface defect detection and low frequency inspection of non-ferrous material.

The WeldCheck 2 is a single channel/frequency instrument that offers a simplified specification but none the less boasts a 10Hz-20MHz frequency range.

The WeldCheck+ is a dual channel/frequency instrument with conductivity for maximum flexibility, with a frequency range of 10Hz-12.8MHz.


  • Single or Dual Channel models
  • Large, Crisp Daylight Readable Display
  • User Friendly Interface and Ergonomic Lightweight Design
  • Industry Standard Probe Connectors
  • 8 Hour Battery Life
  • Rapid 2.5 Hour Charging Time
  • Three-Year Warranty (6-Year Extended Warranty with ETherCover)
  • Advanced Features Loop, Guides and Automatic Lift Off Gain Connection


Lightweight, Rugged and Easy to Use

The WeldCheck weighs just 2.6lbs (1.2kg), has a tough metal outer case and is optimized to resist moist atmospheres. It's 8.5 hour battery life and storage of over 500 readings allows field use for an entire shift without interruption. Additionally, the WeldCheck is equipped with an easy to navigate menu system for rapid function access, including 4 programable, quick access "soft keys" to fit your needs.


Works the Way You Do

The WeldCheck series features a daylight-readable 5.7” LCD Color Full VGA  (640 x 480 pixels) screen, ensuring the operator has excellent signal resolution and presentation no matter what the working conditions are. With the built-in “flip” function, it works equally well for left or right-handed users.


Loop, Guides and Trace Features

"Loop" is a convenient function for capturing live repetitive signals and then optimizing the settings in order to simplify the task of optimizing the parameters.

"Guides" allows the user to display a slide show that can be created easily using 3rd party software. Instructions, tutorials, etc. can be added to the WeldCheck quickly so the inspector can easily switch between the Inspection itself and the Guides while performing a live test.

The "Trace" function allows a reference waveform to be stored on the screen alongside the graticule behind the live spot, allowing the operator to readily compare live data with the reference calibration.



Optional accessories for the WeldCheck include the following:

  • Protective Splash Proof Cover
  • Hard Transit Case
  • Tripod Bracket - To fit 1/4" Camera Tripod Mount with Male Screw
  • External 8 x AA Battery Holder and On/Off Switch
  • Wrist Strap
  • In-Car Power Adapter
  • Leads with various connectors and in various lengths
  • And More
