WHOLE-BODY VIBRATION DOSIMETER User friendly operation and use (even by non-experts) Automatic computation of the exposure levels as defined in the European directive 2002/44/CE Automatic measurement of exposure time Direct assess to the measurement results using a laptop or PocketPC Very short learning curve Reasonable cost Automatic detection and removal of unwanted effects Developed in partnership with INRS (Research Center for Safety, France)

Compliance with standards The EVEC whole-body vibration dosimeter has been developed in partnership with INRS (Institut National de Recherche et de Sécurité, France) under the agreement No.5061249. INRS has verified that this device can be used for whole-body vibration exposure measurements. Acceptance testing has been carried out according to EN ISO 8041:2005, section 12. Each manufactured device is tested according to ISO8041:2005, section 13 Frequency Weightings Wd along X and Y axis Wk along Z axis Those frequency weightings conform to ISO2631 which is the standard referred to for...
