ZIP Zero Interface Probes

Zero-Interface Probes (ZIP) are low-frequency delay-line transducers designed to inspect composite material. The special delay lines used are acoustically matched to the composite material which allows for a zero-interface signal, more efficient energy coupling & transmission, and increased near-surface resolution. Replaceable delay lines are available in packs of five.

ZIP probes are special delay-line contact probes that are single-element longitudinal -wave (straight beam) transducers designed for the detection of near-surface flaws and thickness measurement of thin cross-section materials.
