Rent Casella Micro Environmental Noise Monitor dBadge CEL 352IS

The CEL-352IS is a completely new interpretation of the classic noise dosimeter. It has all the advantages of earlier badge designs such as small size and light weight 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 noise at work measurement protocols during a single run the CEL-352IS will be an ideal instrument for experienced and new user of dosimeters in the workplace. No setup to worry about since the unit stores all results for later investigation and reporting however required.  The CEL-352IS offers more features then the CEL-350 Dbadge.

The CEL-352IS dBadge micro dosimeter is designed to satisfy all current workplace noise protocol methods for the collection of personal noise data. Careful attention to the requirements of US noise dosimetry methodologies provides for the simultaneous storage for the noise levels in such a way that the dose values can be obtained with both 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 OSHA and NIOSH 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. The CEL-352IS will be an ideal unit for industrial hygienists or company safety officers charged with monitoring the noise exposure of workers particularly in situations where a conventional noise dosimeter with a remote cable microphone might not be the most convenient method.
