The company was established in January 1994 by Dr. Klaus Krämer as a specialised firm involved in providing support and developments for the high technology, high frequency Scanning Acoustic Microscopy (SAM). The company´s direction has been primarily aimed at Research, Non-Destructive Testing and the Process Control Industry.

History:
Since 1994 , KSI has established business in more than 20 countries including local sales representatives and agencies. The product lines are high end scanning acoustic microscopes using frequencies up to 200, 400 and 2000 MHz (2GHz) , NDT (Non-Destructive-Testing) routine microscopes and high speed automated ultrasonic systems. 

In October 2007 PVA TePla AG, Asslar, took over the entire KSI Group.
 
 

The first high frequency scanning microscope working with 800 MHz, named ELSAM was introduced by Ernst Leitz Corporation in Wetzlar, 1980 in Germany.  This microscope is exhibit at the German Museum in Munich. In 1989 Dr. Klaus Krämer developed the ELSAM X1 system and the V(z) modul for Ernst Leitz GmbH. In 1994 KSI took over the full product line from Leica formally Ernst Leitz GmbH A family of scanning Acoustic microscopes were developed.  Since then, we have continued to push the technology envelope and provide our customers with superior non destructive acoustic inspection technologies.

In 2000, a family of acoustic microscopes are avaliable for bio med, semiconductor, material research as well as in line industry applications. KSI is the leading manufacture for high frequency non - destructive testing up to 2000 MHz (2GHz) and the high end high precision unique KSI Transducer
