vib^uuork Hand-Arm Vib@work Hand-Arm - the new dosimeter in the Vib@work range developed in collaboration with the INRS. ► Automatic computation of standard exposure values ► Accurate measurement on all types of handheld tools, including highly percussive tools (up to 5000 G) ► Autonomous wire-free miniature sensor Fully compliant with the European Vibration Directive Non intrusive in relation to the normal use of tools Incorporates a mechanism for preventing common measurement errors from occurring ► User-friendly, even for non-experienced users ► Placement of sensors regardless of the primary measurement axis Our innovative measurement system allows vibration measurements to be carried out on vibrating tools using autonomous sensors that don't need to be connected during the measurement process. The data stored by the sensor(s) can be downloaded at the end of the working period by means of a docking The software provided enables the automatic computation and display of standard exposure values as well as a comparison with the values defined in the Vibration Directive. In order to cover the full range of existing handheld tools, two sensors can be used: one for standard vibra- ting tools and another intended for highly percussive to- ols that exhibit high shock levels. (Up to 50 .000 m/s2). This measuring system, which can be attached to any kind of tool, is currently the only one of its kind capable of taking accurate vibration measurements without disrupting workers'tasks with annoying and fragile wires. A special version of the sensor is specifically designed for measurements on highly percussive tools. Developed in collaboration with the

Hand-Arm Description of the sensors The hand-arm vibration dosimeter comprises a miniature case that p comprising: a vibration sensor (standard sensor or sensor for highly per cussive tools depending on choice); a 3-axis accelerometer ; an electronic circuit that is able to acquire, process (weighting (weighting ig g a compact battery a communication circuit to access stored values (not used during measurement) a status light (LED) The range includes two sensors that are identical in terms of aesthe aesthe e tics and operational features but o er d erent characteristics: s surements on highly...
