Description

Ideally suited to a wide range of industrial noise measurement applications, the CEL-620 Sound Analyzer uses the latest technology to give high standards of performance in a compact design. The CEL-620 meter is designed to satisfy this need and to enhance it by providing the capture and display of the highest maximum level and lowest maximum level together with the integrated time average level.

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.

The CEL-620 Sound Analyzer series was designed with ease of use in mind. The menu structure is designed to pick up and use without the use of a manual. A simple icon structure is used with word prompts for each selection. The instruments has six selectable set-ups. Four pre-defined set-ups can be used to satisfy local workplace noise legislation. Two user set-ups can be defined to display parameters and weighting as required.

Regardless of the setup used, the 620 measures and stores all parameters and weighting even if not selected. These can be viewed if necessary on the software. Up to 100 measurements can be stored without the need to download. All runs are date and time stamped. When connected to a PC via the USB connection, the 62x acts like a memory card, so data files can be moved to a PC and easily reviewed without the need for software.

All 62x models are integrating to measure average noise levels as well as peak levels for workplace noise legislation. CEL-620A model also simultaneously measure Lc and La used within the HML method for selection of hearing protection. In addition, the CEL-620B model performs real time octave and analysis from 16Hz to 16kHz, values which are used in the octave band method for selection of hearing protection. If future requirements change, any instrument can be upgraded to a higher model without returning to Casella.
