Calibration service: Electrical measurands

Calibrating signal conditioners. Providing precision measurements.

Signal conditioners help to provide precise measurements that are essential for accurate data gathering or for machine control systems. These instruments convert an electrical or mechanical input signal into other forms of output signal. The aim of the conditioning is to amplify the signal and convert it into an easily readable and compatible form for data collection.

While electrical calibrations usually start from frequencies of 10 Hz, we offer electrical calibration of your measuring equipment in low frequency ranges starting from 0.1 Hz.

Trust SPEKTRA for the electrical calibration of your signal conditioners and your vibration control systems.
