Many industrial measurements of complex noises require a complete knowledge of the variable noise level climate over a period of time. The CEL-620 sound level meters are designed to satisfy this need and to enhance it by providing the capture and display of the highest maximum level and the lowest minimum level together with the integrated time average level.
A super wide 140 dB dynamic range means that the user does not need to worry about changing scales as it will always be on the right scale. The provision of all the popular frequency and time weightings allow many different measurements to be taken by new and experienced users alike. The full-color, high-precision, graphic LCD enhances the user experience with this new meter.
The all new CEL-620 sound level meters feature a large 240 x 320 pixel full color graphic display that helps the user interpret the changing noise climate and measure it correctly. All of the popular noise parameters are measured and stored (model dependant) such as current sound level, maximum, minimum, time average, peak and TWA (with optional threshold). Careful design and use of the modern DSP technology allow for the simultaneous capture of these sound parameters with A, C and Z frequency weightings, Slow, Fast and Impulse time responses over a full 120 dB dynamic range.
The CEL-620 models feature data storage for the collection of overall run summary data plus statistical LN% values in the CEL-621 models. When connected to a computer the instrument appears as a mass storage device and can be accessed as if it were a USB thumb drive, This allows the measurement data to be easily transferred to popular spreadsheets or other office documents with out the need for proprietary software.
