ETher ETherCheck EC & Bond Tester

ETher ETherCheck EC & Bond Tester

Combined Eddy Current & Bond Testing Flaw Detection

Twice the Functionality in One Instrument

The EtherCheck is a combined Eddy Current and Bond Testing Flaw Detector. It comes with a rich range of features offered by a best in class eddy current flaw detector combined with the most widely used acoustic bond testing method; Pitch-Catch. Features a single frequency range of 10Hz-20MHz and dual range of 10Hz-12.8MHz.

All functions are in a single lightweight instrument with a common user interface between the two modes, resulting in simple operator led set up.

ETherCheck Pitch-Catch Probe

Ergonomically designed and manufactured from CNC machined Aluminum with rubber hand grips, the EtherCheck Pitch-Catch probe is both comfortable to use and suitably robust.

The transmitter and receiver sensor guide feet can be positioned by the operator to suit the inspection task. The transmit and receive probe tips are interchangeable with rounded and flat tip profiles available. The sensors are positioned close to the edge of the housing to allow inspection in tight areas.

The EtherCheck Pitch-Catch Probe offers Automatic Probe ID by storing its own default settings which can be programmed by the operator. The EtherCheck also works with other manufacturers probes.

  • Includes General Eddy Current, Rotary, Conductivity and Pitch-Catch
  • Pitch-Catch dry coupled bond testing mode allows rapid detection of defects in laminate, bonded and sandwich structures
  • Automatic Test Frequency Optimization
  • Waveform, Time-base and Phase / Frequency Plots
  • Large, Crisp Daylight Readable Display
  • User Friendly Interface and Ergonomic Lightweight Design
  • Advanced Features Loop, Guides, Dual Frequency Auto-Mix



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.


Fully Featured Instrument

Loop, Guides, Trace, Rotary Capabilities, Conductivity and More

"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.

Includes "Rotary Capabilities" as standard and can be used with the ETher Mercury (mini) ARD002, Hocking 33A100 or the Rohmann MR3/SR1 and SR2 Drives (with special adapter cable).

"Conductivity Mode" - when connecting the Conductivity Probe, the instrument auto-detects the probe and seamlessly switches into conductivity mode. Removal of the probe switches the instrument back to flaw detection mode.



Optional accessories for the WeldCheck include the following:

  • Protective Splash Proof Cover
