CEL-632 and CEL-633 are available as IEC61672-1 Class 1 or Class 2 sound level meters. They come with complete accessories, including sound calibrator, carrying case, wind screen, user manual and USB cable.
CEL-633 additionally stores "statistical parameters" (Ln%) for environmental noise evaluation. Five adjustable percentiles are available.
The sound level meters allow frequency analyses in octave bands (16Hz – 16kHz) or 1/3 octave bands (12.5Hz – 20kHz). 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-63X sound level meter features a USB interface which may be used for data storage in a Microsoft Excel-editable format. Alternatively the data may be downloaded with the Casella Insight software.
63X series model selection
You may select one of two models. Please refer to the selection table containing the model features. The optional octave band analyzer is identified as follows:
'A' without octave band analyzer
'B' for octave band analyzer
'C' for 1/3 octave / 1/1 octave band analyzer.
Each instrument comes with a standard accessory case, wind screen and calibration certificate.
