Who we are

Leading in coordinate metrology with optics, probe, computed tomography and multi-sensor systems

Coordinate measuring machines are used to measure geometrical characteristics of workpieces such as lengths, angles, diameters or even complex position tolerances. Machines with several sensors, e.g., image processing, laser and probe, are called multi-sensor coordinate measuring machines.

Werth concentrates on the development, manufacture and sale of coordinate measuring machines with optics, probe, computed tomography and multi-sensor systems as well as the measurement of micro-features. The company's global technology leadership in these market segments is reflected in a number of world firsts and patents on instrument technology and sensors. The achievable accuracy of Werth machines can be in the range of a few micrometers or, in the case of highly accurate systems, even in the range of a few 10 nanometers, making Werth the world leader in multi-sensor coordinate measuring machines.

Comprehensive services to support users in the application of the machines complement the field of activity and create a high level of customer satisfaction. The quality management system according to DIN EN ISO 9001 and the DAkkS laboratory for the calibration of coordinate measuring machines according to DIN ISO 17025 guarantee the reliability and accuracy of the machines. In 2003, Werth pioneered the development of accreditation procedures for laboratories with multi-sensor coordinate measuring machines together with the PTB. In July 2013, the DAkkS laboratory of Werth Messtechnik GmbH was also the first facility of its kind to be accredited for the calibration of coordinate measuring machines with X-ray tomography sensors.

More than 10,000 Werth coordinate measuring machines are installed worldwide in a wide variety of industries. Examples of application fields for these machines are: Aerospace industry, automotive industry, electronics industry, jewelry manufacturing, watch industry, tool making, plastic injection molding, medical technology, turbine construction as well as aluminum and plastic extrusion.

"Leading in coordinate metrology with optics, probe, computed tomography and multi-sensor systems"

Our history

Experience from over 70 years of company history forms the basis of our success

Over 70 years of company history are characterized by innovative new developments in the field of coordinate metrology with optics, probe, computed tomography and multi-sensor systems. The first profile projector in console design set standards in terms of ergonomics and precision as early as 1955. In the 1960s to 1980s, measuring projectors with the Werth Tastauge and digital displacement measuring systems were further developed into optical CNC coordinate measuring machines. In 1987, Werth Messtechnik introduced the first multisensor coordinate measuring machine with image processing and integrated laser distance sensor under the name Inspector®. With the introduction of the VideoCheck® product line in the 1990s, Werth once again pioneered the introduction of digital image processing into industrial coordinate metrology. In 2005, the TomoScope® was introduced, the first machine with computed tomography developed specifically for coordinate metrology. Today, X-ray computed tomography and various optical and tactile-optical as well as conventional tactile-electrical sensors, some of which are patented, are used for multisensor coordinate measuring machines. The range of devices extends from measuring machines for production monitoring to highly accurate multisensor coordinate measuring machines with measurement errors of just a few tens of nanometers.
