Compact Vibrometer 107Â

FFT Vibrometer - 107Â is a compact, handheld, microprocessor based vibration-measuring instrument designed to measure vibration parameters of the rotating machine according to ISO 10816, as well as other international standards which have been set on the same level - vibration acceleration, RMS vibration velocity, vibration displacement and Vibration spectrum analysis in FFT. It allows to measure the dynamic signals followed up by the record it into the non-volatile memory, as well overview and analyze the spectrum.
