Within the RAM-5000 series the SNAP system has been developed specifically for research on non-linear acoustic phenomena. Some examples of important applications include: metal fatigue, micro cracking, bond strength of adhesives, metal embrittlement, and properties of coatings. The RITEC SNAP incorporates a number of unique circuits designed to facilitate the determination of these properties using a variety of techniques. A standard SNAP system consists of the following modules. However, specific adaptations to your special measurement needs are possible. Please do not hesitate to contact us.
