VM31 – Human Vibration Analyzer
The VM-31 Human Vibration Analyzer from MMF makes a versatile tool for the measurement of human response to vibrations, condition monitoring of machinery or as vibration meter and frequency analyzer for other applications requiring single or tri-axial vibration measurements.
The meter’s compact design with a colored OLED display allows for quick and user-friendly operation.
For hand vibration measurement according to ISO 5349 and ISO/TR 18570, whole body vibration measurement according to ISO 2631 and ship vibration according to ISO 20283-5.
Display of running and interval RMS value (RMS), maximum RMS value (MTVV), vibration dose value (VDV), vibration total value, peak value, and maximum peak value.
Three-channel FFT for finding main frequencies.
