Hidden internal flaws can be identified in engineering materials like metals and composites. Wall thickness of pipes, tanks, and a wide variety of manufactured parts can be measured from one side. Material, time, and labor can be saved in many applications where the internal structure is invisible and the opposite side is difficult or impossible to reach.
Non-Destructive Testing is accurate, reliable, and repeatable. Testing can be performed by transmitting ultrasound or inducing eddy current into a material from one side, without the need of cutting or destroying parts.
A common application of NDT is the wall thickness measurement of a wide variety of manufactured parts, such as pipes & tanks. NDT is also essential for detecting any kind of imperfection, such as cracks or discontinuity. The test is repeatable, accurate and reliable. NDT can be performed by transmitting ultrasound or inducing eddy current into an equipment from one side, which helps users avoid cutting or destroying parts of the equipment under test.
Our innovative nondestructive testing instruments are used in industrial and research applications, ranging from aerospace, energy and automotive to consumer products. Our leading edge technologies include ultrasound, ultrasound phased array, eddy current, and eddy current array.
NDT Applications

* Thickness measurement
* Material characterizations
Ultrasonic testing
Ultrasonic testing uses high frequency, highly directional sound
waves to measure material thickness, find hidden internal flaws, or
analyze material properties in different materials such as metals, plastics, composites, ceramics,
rubber, and glass. Using frequencies beyond the limit of human hearing,
ultrasonic instruments generate short bursts of sound energy that are
coupled into the test piece, and then the instrument monitors and analyzes
reflected or transmitted wave patterns to duly generate the test results.
Phased array testing
Phased array testing is a specialized type of ultrasonic testing that uses sophisticated multi-element array transducers and powerful software to steer high frequency sound beams through the test piece and map the returning echoes; subsequently, the instrument produces detailed images of internal structures similar to medical ultrasound images. This testing is used for the inspection of critical structural metals, pipeline welds, aerospace components, and similar applications whereby the additional information supplied by phased array inspection is valuable.
Eddy current testing
Eddy current testing utilizes principles of electromagnetic induction to locate near-surface cracks, measure thickness, and categorize certain material properties in metals. An eddy current probe generates a magnetic field that induces currents that flow in a circular path in the test material. Changes in the integrity or thickness of the test piece will in turn affect current flow, the magnetic field, and ultimately the magnitude and phase of the voltage in the coil. The instrument monitors the probe output and displays information for analysis.
