About Krautkramer


Do you know what happens when you make great quality products?  Your brand became a household name and lives on even after your company no longer exists.  That is what happened to Krautkramer, the company.  Even after changing ownership twice, the name is still used decades later.

Krautkramer was a leading maker of ultrasonic non-destructive testing machines for many years before it was purchased by General Electric Inspection Technologies which later changed to Waygate Technologies with about 125 years of industry experience.

The majority of Krautkramer products were continued within the Waygate Technologies umbrella.  However, some ultrasonic flaw detectors under the brand name Krautkramer are still in the market and are supplied by different companies around the world.
