Casella dBadge Micro Noise Dosimeter LCeq & L(C-A) 1 Pack Kit

CEL-352-K1 dBadge Micro Noise Dosimeter LCeq & L(C-A) 1 Pack Kit by Casella

The CEL-352 PLUS is a completely new interpretation of the classic noise dosimeter. It has all the advantages of earlier CEL dBadge badge designs such as small size and light weight and in addition it offers the direct calculation of the LC-La value. Fully featured and able to satisfy all current noise at work measurement protocols during a single run the CEL-352 PLUS 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

• Calculates all the popular noise dose parameters
• Calculates the LC-LA value
• 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 ½” cavity

Applications

The CEL-352 PLUS 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 5 and 3 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 and the Lavg & TWA for the run. The CEL-352 PLUS model also calculates and stores the L(C-A) value based on the whole run. The CEL-352 PLUS will be an ideal unit for industrial hygienists or company safety officers charged with monitoring the noise exposure of workers 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 Plus can run for up to 28 hours giving nearly 4 full 8- hour shifts under normal conditions. A 30 min charge will give adequate operational time for an 8-hours run. An integral 2-line display shows the noise results and confirms the calibrations before and after the run. The unit can be locked to prevent tampering by the wearer.

A brand new dedicated download database program called Insight compliments the dBadge Plus 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 Plus to identify units in multiple measurement kits.
