Based on years of continuous research and development, as well as cooperation with the Physikalisch-Technische Bundesanstalt (PTB) and Polytec, SPEKTRA has taken the lead in the world market for primary calibration systems for acceleration sensors and laser vibrometers.

The highest level of precision and a calibration traced back to an absolute physical measurand are the main reasons for utilizing a primary calibration system. National Institutes of Metrology (NIM) around the world are the main customers of primary systems, and many of the NIMs worldwide are satisfied customers of SPEKTRA CS18P primary calibration systems.
