NEW!! - CEL-610 Wide Range Sound Level Meter from Casella USA

Introduction Many basic noise measurements require a simple "quick look" to see what is currently happening. The CEL-610.A meter is 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 a real time bar graph display. A super wide 120 dB dynamic range means that the user does not need to worry about changing scales as it will always be on the correct scale and the provision of all the popular frequency and time weightings allow many different measurements to be taken by new and experienced user alike. A full color high precision, graphic LCD enhances the user experience with this new meter. Applications Noise measurements with traditional sound level meters have always been a tricky task due to the need to make sure that the right range is selected.

This is completely eliminated in the all new CEL-610 meter because of an incredibly wide dynamic range capability. The single range covers all noise levels from 20 to 140 dB in one setting. This eliminates the worry of overloads or under range signals during the measurement. Careful design of the circuitry in the CEL-610 using the latest digital signal processing (DSP) technology ensures that everything can be measured simultaneously. The measured parameters include the current sound level, the maximum and the minimum sound levels. A non decaying hold feature enables the user to gain a better understanding of the noise level climate than was previously possible at this price point. The large color graphic display, unique to such a low cost meter, is used to excellent benefit to show the key measurement parameters easily and clearly on a quarter VGA size screen. A simple context sensitive menu is provided to control the functions of the CEL-610. The menu itself can be customized by the user to have the screen messages available in English, French, Spanish or other major language as required.
