Ultrasonicator

Ultrasonic is sound beyond the human audible range that is 20 to 20 kHz. Ultrasonic inspections use frequencies of above 0. 5 MHz up to 25 MHz to test metals, ceramics, glass, composite and other engineering materials. Ultrasonic testing is commonly used for inspecting castings, rolled bars, plates, forgings, thin sheets, extruded components, drawn components, welds and to measure reduction in thickness of pipes, vessels and other components
