The CEL-350 dBadge Series comprises of the CEL-350 dBadge, the CEL-350L dBadge 'Lite' and CEL-352 dBadge 'Plus'. The CEL-350 dBadge Series is ideal for personal noise exposure measurements around the workplace. By using the latest digital technology, the CEL-350 dBadge Series achieves new standards of performance levels in noise dosimetry.

The dBadge design eliminates cables, unlike traditional dosimeters, and weighs only 71g. No other external equipment is needed to operate the CEL-350 dBadge Series. It is simply operated by the 2 keys on the side of the instrument.

Battery life and memory capacity are sufficient to perform many consecutive shift measurements without charging or downloading. Recharging the integral NiMH battery can be achieved in 90 minutes. A variety of mounting options are available for all types of working conditions, making the CEL-350 dBadge Series very easy to fit to the shoulder of the employee and comfortable to wear.

The CEL-350L 'Lite' measures and stores all necessary workplace noise parameters simultaneously. The CEL-350 dBadge model has additional functionality to measure the time history of noise levels on top of these cumulative levels, which can later be graphed on the PC Software.

The CEL-352 dBadge 'Plus' model is also available which measures simultaneous 'C' and 'A' weighted Leq measurements as additional functionality. These can then be used to calculate the effectiveness of hearing protection by either the SNR or HML method further increasing the applications for this innovative product. For any model no set-up is required so there is no risk of measuring the wrong parameters.
