CEL Acoustic Calibrator 350

Pine Item #51421

The CEL-350 dBadge Series is the first compact noise badge product to be designed with a display. This internal display makes it easy to perform calibration, provides status information and shows key measured data. The dBadge has a unique ‘fuel gauge’ to display memory and battery status, ensuring the exact remaining battery and memory capacity can be viewed on the display. Also a unique feature of the dBadge is the alarm function. An ultra-bright LED on the dBadge gives a visual indication of when exposure action levels have been exceeded by flashing at different rates. These action levels can be configured via the Insight software and used to instantly see if noise control or hearing protection measures are needed. The alarm function can be switched on or off via the dBadge keys. In addition to noise exposure parameters, the time history of the noise is logged in 1 minute values of both the average noise level and the peak value for subsequent analysis of how the noise exposure has occurred. This data can be viewed and analysed via Insight software.
