Curved array probes are made with a corrosion-resistant stainless steel case and are guaranteed waterproof up to 1 m underwater. The acoustic impedance of these probes matches water. They are compatible with adjustable immersion wedges and are used for the inspection of carbon fiber reinforced polymers (CFRP) corners and in addition to the inspection of composite for delamination.
Immersion probes are designed to be used with a water wedge or in an immersion tank when the test part is partially or wholly immersed. They are longitudinal wave probes that can be set up for refracted shear-wave inspections using a Rexolite wedge.
