CEL-350-7 7 x dBadge Micro Noise Dosimeter (supplied with w/scrn, cal cert, pin and alligator clips) by Casella

The CEL-350 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 asingle run the CEL-350 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.

Key Benefits

  • Lightweight less than 2.4 oz
  • Small size only 2.8 in long and 1.7 in wide and 2.0 in tall
  • Quick battery recharge in less than 90 mins from completely empty
  • Stores everything for later review
  • Calculates all the popular noise dose parameters
  • Time history profiling of 4 results at fixed 1 m intervals
  • Wide dynamic range from 65 to a full 140 dB
  • Measures simultaneously 3 dB and 5 dB exchange rates
  • Lockable for security
  • Direct automatic calibration with standard acoustic calibrator with cavity

Applications

The CEL-350 dBadge micro noise dosimeter is designed to satisfy all current workplace noise protocol methods for the collection of personal noise data. Careful attention to the requirements of both US and European noise dosimetry methodologies provides for the simultaneous storage of 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 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 plus the Lavg & TWA for the run. The CEL-350 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.

Operation and use

A simple drop in rapid battery charger system provides a quick 90 min maximum recharging time for the built in NiMH battery pack. The dBadge can run for up to 28 hours giving nearly 4 8-hour shifts under normal conditions. A 30 min charge will give adequate operational time for a full 8-hours run. An integral 2-line display shows the main noise results and confirms the acoustic calibrations before and after the actual run. The unit can be easily locked to prevent tampering by the wearer.

A brand new dedicated download database program called Insight compliments the dBadge system allowing all the stored data to be downloaded and analyzed according to whatever format the user requires. Multiple reports can be obtained from the same data without needing to remeasure the noise. This saves both data collection time and analysis time on the pc. Unique identities can be uploaded to the dBadge to uniquely identify units in multiple measurement kits.
