The CEL-350 is a completely new interpretation of the classic noise dosimeter. It has all the advantages of earlier badge designs, and yet it still provides all of the benefits that users have come to expect from a traditional noise dosimeter. Fully featured and able to satisfy all current workplace measurement protocols during a single run, the CEL-350 will be an ideal instrument for experienced and new users of dosimeters in the workplace. There is no setup to worry about since the unit stores all results for later investigation and reporting - however required.
The dBadge is designed to satisfy the requirements of both US and European noise dosimetry methodologies. It provides for the simultaneous storage of the noise levels in such a way that dose values can be obtained with the widely used exchange rates (or Q factor) using the 3 and 5 dB doubling rates. This means that a single measurement run can be taken and the noise levels assessed to both the US OSHA and the NIOSH or the European ISO legislation. Four time history profiles are saved with the Q=3 and Q=5 time average value plus the C and the Z peak levels. The dosimeter calculates and displays the % noise dose value plus the Lavg for the run.
These dosimeters are approved for use in hazardous areas and have been granted IS approval (ATEX number Sira 07ATEX2032X). They are also classified for use in Class 1, Div 1, Groups A, B, C and D T4 (FM report 3029871).
