Air-Coupled Ultrasonic Tester ACT20

The ACT20 air‑coupled ultrasonic flaw detector is a portable instrument that supports the operation of non‑contact air‑coupled ultrasonic transducers across a frequency range of 50 kHz to 2 MHz. It is powered by a replaceable lithium‑ion battery, providing up to 8 hours of continuous operation and making it well suited for field applications. The device accommodates both transmission‑mode and guided‑wave testing, enabling the detection of internal and surface defects in composite materials, adhesive‑bonded structures, and similar substrates.
