TRD - Near field probe
The near-field probes offer excellent detection of internal corrosion, erosion, and axial cracking and return high-quality, amplitude-based signals that enable fast and simple data analysis. There is no need for a reference probe or extension. These probes are ideal for fin-fan carbon steel tube inspection.
Features
- Ideal for carbon steel fin-fan tubes.
- Excellent detection of internal corrosion, erosion, and axial cracking.
(Not recommended for detecting OD defects.) - No need for a reference probe or extension.
- High-quality, amplitude-based signals.
- Fast and simple data analysis.
Faster is better - Available for shortest delivery times
