Twin Crystal Ultrasonic Probe – Corrosion & Near-Surface Accuracy

The Twin Crystal Ultrasonic Probe (Dual Element) is engineered for improved near-surface resolution and enhanced performance in corrosion inspection applications.

Featuring separate transmitting and receiving crystals mounted at an angle, this probe reduces dead zone limitations and provides stronger, more stable backwall echoes in thin and degraded materials.

It is the preferred choice for technicians performing corrosion monitoring, remaining wall thickness assessment, and inspections where surface condition impacts signal clarity.

Ideal For

• Corrosion and erosion inspection

• Thin wall thickness measurement

• Pitted or scaled surfaces

• Painted or coated materials

• In-service asset monitoring

Why Twin Crystal?

Standard single-element probes can struggle in near-surface regions. Twin crystal probes are designed to overcome that limitation.

• Improved near-surface detection

• Reduced dead zone

• Stronger, more stable backwall signals

• Better performance on rough or corroded surfaces

• Increased measurement confidence

This design improves signal separation between initial pulse and backwall echo, delivering clearer A-scan interpretation and more consistent thickness readings.

When corrosion matters — resolution matters more.

Reliable. Repeatable. Inspection-Ready.
