This Casella data logging digital impulse sound level meter is a completely new design of sound level meter featuring the power of Digital Signal Processing (DSP) technology and the simplicity and low cost of a traditional analog instrument. It can be used for a wide range of noise measurement tasks and is suitable for many everyday tasks. Complying with all the ANSI and IEC accuracy specifications in the Type 2 category the CEL-242 will appeal to new and experienced users alike. This unit is capable of storing 419,000 data points. Data is stored as files compatible with spreadsheet software packages (.csv format) and can simply be transferred via USB then graphed as required with any standard package.
