The CEL-620 is available as IEC61672-1 Class 1 or Class 2 sound level meter. It comes with complete accessories, including sound calibrator, carrying case, wind screen, user manual and USB cable.
The sound level meter provides the means for octave band frequency analyses (16Hz – 16kHz). The analysis is performed in real time with a measuring range of 140dB. Therefore it is not necessary to change the measuring range. The CEL-620 sound level meter is equipped with a USB interface. Stored data may be exported in a Microsoft Excel-editable format. Alternatively the data may be downloaded with the Casella Insight software.
