Impact Hammer

Impact Hammer

The IH series IEPE impact hammer range features a rugged force sensor that is integrated into the hammers striking surface. The force sensor serves to provide a measurement of the amplitude of the energy stimulus that is imparted to a test object. A variety of tips supplied with each hammer permit the energy content of the force impulse to be tailored to suit the requirements of the item under test. IH series impact hammers can be applied for Structure Health Testing, Resonance Determination, Modal Analysis, etc.
