Sonatest PMAP3737445T 3.7 MHz 37-Element 45° Phased Array Mini Angle Probe, Weld Inspection and Flaw Detection

Sonatest PMAP3737445T 5 MHz 0.375" 45° Shear Wave Angle Beam Probe

The Sonatest PMAP3737445T is a 5 MHz shear wave angle beam probe designed specifically for high-performance weld inspection, flaw detection, and non-destructive testing (NDT) of steel structures and pipelines. Featuring a compact 0.375" (9.5 mm) lead zirconate titanate crystal and a fixed 45° refracted angle, this probe delivers sharp, accurate detection for weld toe and root coverage.

Its precision-focused design with a robust acrylic face and top-mounted connector makes it suitable for integration into harsh industrial jobsites. The PMAP3737445T is compatible with leading Sonatest flaw detectors: Wave, Sitescan D-50, Masterscan D-70 / 700M, and Prisma—ensuring seamless NDT workflow for welders, inspectors, and engineers.
