New Cable-Free Personal Dosimeter with Intrinsic Safety Approval

Quest Technologies, a 3M company (USA) is pleased to announce the release of The Edge eg5 model, an intrinsically safe cable-free personal noise dosimeter featuring simultaneous C and A weighted measurements. The eg5 model has been independently tested and certified by Simtars of Australia to meet the IECEx ia I/IIC 143°C IP65 marking.* Simtars is an accredited test laboratory and certification body for international (IECEx) certification schemes. This IECEx Certificate of Conformity states that the eg5 personal dosimeter is rated intrinsically safe for use in a potentially hazardous atmosphere. Simultaneous C and A weighted measurements allow for calculation of C-A to aid in hearing protection selection.

The eg5 model serves as a personal dosimeter, time-history monitor, survey monitor and peak dosimeter. Its cable-free design with ¼” mounted microphone eliminates cables interfering with the task at hand. Weighing in at three ounces, this compact shoulder-mount instrument conforms to the worker’s body for comfortable use while maintaining an upward orientation for the microphone. Its large (128x64) LCD screen can be configured to display SPL, Dose, Lavg or Leq, TWA, Max Level, Min Level, Peak Level, Exposure and Run Time.    A rechargeable lithium polymer battery provides the eg5 model up to forty hours of battery life. Recharging the unit is simple with the 1- or 5- bay “EdgeDock” docking station. As the unit is recharging, data can be downloaded from the dosimeter and sent to a PC via the EdgeDock’s USB Port. Data measurements can then be managed and analyzed with QuestSuite.
