This is the Casella CEL632C2 Class 2 1/3 Octave Sound Meter Kit which has an advanced automatic timing, time history storage and real-time 1/3 octave band filters which means that it is suitable for detailed, long-term occupational noise assessments. The CEL632C Sound Level Meter also measures all the parameters needed for a successful survey of workplace noise. The main parameters are Leq, Peak, Lmax, Fast, Slow and they are all measured simultaneously. There isn't any need to select a measurement range as they have a single span from 20 to 140dB.
The CEL632C is a data logging meter that does not require any additional software - when plugged into a computer it acts like a memory card. You can manually copy the data to your computer or load it into a spreadsheet program using a small conversion application. However, the Insight software makes this process more convenient, links the measurements to person, place or process, and presents the results graphically. We recommend the Insight software with the CEL632C if you are going to take advantage of the Time History store or if you will be making regular use of the 1/3 octave band filters. In these cases processing the large amounts of data in a spreadsheet can be rather time consuming.
