To address the issue of assessing individual noise exposure, dosimeter Wed007 and software dBLexd are the solution compliant with European Directive 2003/10/EC.

Based on a multiple-point metrological approach, the technical solution consists in deploying a set of "blind" dosimeters in the work place, which are operated with a remote control using wireless communication. This simple and non-invasive device is a valuable tool when implementing new regulations on the field.

Wed007 consists of an ergonomic and miniaturised housing, hosting acquisition unit, signal processing, data storage and data transfer. Only a single remote control of the Pocket PC type, dBWed, is required to drive 5 instruments at the same time. Noise measurement performance, electronic power and simplicity of the user interface, combined with Bluetooth wireless communication technology, make Wed007 the must-have device for optimum compliance with European Directive 2003/10/CE.
