A manual excitation with a small Modal hammer without a „Double Hit“ is nearly impossible – a well-known and very inconvenient issue. As a 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 hammer from MAUL–THEET includes the vImpact–20 and the vImpact–60. The difference lies mainly in the performance of the measuring range – the vImpact–60 to max. 60kHz, the vImpact–20 measures up to 20kHz.
