Advantages of Dual Linear Array and Dual Matrix Array Probes

• Excellent signal-to-noise ratio
• Higher frequencies and smaller elements provide benefits for applications requiring detection of very small indications

• Ability to transmit and receive longitudinal waves in granular materials
• Increased penetration in stainless steel, including austenitic, corrosion-resistant alloys, and dissimilar welds
