A manual excitation with a small Modal hammer without a „Double Hit“ is nearly impossible – a well-known and very inconvenient issue. As solution for this issue MAUL-THEET developed the product family of the automatic Modal hammer „vImpact“. This enables you to precisely and reproducibly excite structures and measure the excitation forces. The series of automatic Modal hammers from MAUL–THEET includes the vImpact–60 and the vImpact–20 and the vImpact–2000 . The difference between the hammers are the frequency ranges and maximum forces. Especially the vImpact-2000 is adjustable for a wide range of force levels.
