Top-of-the-line Multi-frequency Multi-parameter Multi-channel electromagnetic comparator with real-time harmonic analysis at each of up to 32 test frequencies. Industry 4.0 ready!
Encircling / Segment coil: Transverse Defects
![Swiveling yoke houses a segment test head for inspection of welds in large pipes.](https://i0.wp.com/www.technofour.com/wp-content/uploads/2022/09/Magnetizing-yoke-with-swivelling-mechanism.png?fit=169%2C300&ssl=1)
Top-of-the-line Industry 4.0 ready system for inspection of metal tubes, bars and wires for surface defects. Simultaneous multi-frequency option and proprietary D3 signal processing make for enhanced inspection.
Rotating Probes:
Longitudinal Defects
![Rotating heads house four probes for inspection of bars and seamless tubes for longitudinal defects](https://i0.wp.com/www.technofour.com/wp-content/uploads/2022/09/RH3.jpg?fit=294%2C300&ssl=1)
Specially designed to inspect bright or black bars or seamless tubes for longitudinal defects. Can be combined with an encircling channel for comprehensive inspection.
In-service Inspection of
Heat Exchangers
![INSIS-EX is a veritable swiss knife of eddy current testing. There is little that it cannot do.](https://i0.wp.com/www.technofour.com/wp-content/uploads/2022/09/InsisEX.jpg?fit=300%2C160&ssl=1)
Top-of-the-line versatile simultaneous multi-frequency, multi-channel, instrument for in-service inspection of heat exchangers / steam generators / RFEC and static / dynamic eddy current tests, conductivity and coating thickness measurement
Eddy Current
Component Cracks
![Defectoscope Test System](https://i0.wp.com/www.technofour.com/wp-content/uploads/2022/09/DFSEX.jpg?fit=300%2C256&ssl=1)
Finished components can be scanned by a probe as the components rotate, thus inspecting the entire surface helically. Automation can be customized.
