The Svantek SV 106 Six-channel Human Vibration Meter and Analyser meets requirements of ISO 8041:2005 standard and it is an ideal choice for measurements according to ISO 2631-1,2&5, ISO 5349 and directive 2002/44/EC of European Parliament. This revolutionary, pocket-size instrument enables simultaneous measurements with two triaxial accelerometers (e.g. both-hands vibration or triaxial SEAT transmission measurements are possible).

The ISO 2631-1 specifies different weighting filters and indicators for evaluation of effect of vibration on human health, comfort and perception. In accordance with ISO 2631-1 and European Directive the A(8) vibration exposure value is calculated as the highest value of frequency weighted RMS determined in 3 axes including the weighting factor of 1.4 in the X and Y axes. ISO 2621-1 also suggest to use VDV instead of RMS if the signal is impulsive which is recognized by the ratio of PEAK to RMS being higher than 9 (so called crest factor). Therefore vibration exposure limits are specified as action values and limit values both for RMS and VDV.

Using computational power of its digital signal processor, the Svantek SV 106 can perform 1/1 or 1/3 octave real-time analysis simultaneously to the meter mode.Advanced time-history logging and time-domain signal recording (according to the ISO 2631-5) to the microSD flash card offer a great data input for detailed signal analysis.

Results can be easily downloaded to PC using USB interface. The instrument works with Svantek’s specialist health and safety software package, “Supervisor”, and also with the full analysis package SVAN PC++.

The whole-body vibration measurement is easier thanks to SV 38V seat-accelerometer which can be placed directly on the seat cushion, floor or fixed to the back of the seat. The SV 105A set with triaxial accelerometer enables hand-arm vibration measurements regardless of the type of evaluated tool.
