Human Vibration

Triaxial Human Vibration Meter	VM30-H
For hand-arm vibration measurement to ISO 5349, whole-body vibration to ISO 2631, BS 6841 or ANSI S3.18 and ship vibration to ISO 6954 Machine vibration can be measured as acceleration, velocity or displacement with selectable frequency ranges between 0.4 Hz and 10 kHz Display of true RMS, maximum RMS (MTVV), interval RMS, vibration dose (VDV), total vibration value (aW), peak, maximum peak and crest factor Memory for over 1000 measurements with PC interface Well suited as vibration dosimeter due to its small dimensions, waterproof design and long battery lifetime	Human Vibration Meter VM30-H VH30-HAWB kit for hand-arm and whole-body measurement VM30-H: Triaxial RMS display VM30-H: Display of total vibration value Ahv VM30-H: Loading stored settings VM30-H: Selection of measuring mode VM30-H: Filter selection VM30-H: Sensor selection VM30-H: Saving a measuring value VM30-H: Connectors VM30-H: Batteries VM30-H: Rear view Please click for details
