Detailed description
The JQB-WV wave velocity tester is a professional instrument specifically designed for rock wave velocity testing. It features meticulous craftsmanship, high detection efficiency, and the ability to calculate wave velocity and amplitude on-site. It is suitable not only for rock mass wave velocity testing in engineering construction but also for indoor experimental wave velocity testing and research on small-scale rock specimens and metal parts, providing an effective means of non-destructive testing for stone building components, etc. It can comprehensively reflect various information about the rock (joints, fissures, strength, etc.). It is the preferred instrument for engineering testing units and universities.
