Casella, CEL-620.B2, Broadband and Octave Band Sound Level Meter (Class 2)Includes:Sound level meterWindscreenWrist strap3 x AA batteriesCMC51 USB interface cableCalibration CertificateThe CEL-62x Series of Integrating Digital Sound Level meters can be used for the measurement of all workplace noise parameters to comply with workplace noise legislation, e.g. EU, OSHA and ACGIH. Use the CEL-62x Series to carry out occupational noise assessments or machinery noise tests as well as to assist with the selection of hearing protection. The CEL-62x is a simple to use meter and data is displayed on the high resolution colour display. Measurement screens are intuitively colour coded according to the mode of operation, i.e. green if a measurement is being taken and red when a run has ended. Data is graphically displayed to give a clearer picture of the noise environment. Calibrate easily on-site with the 120 Series Calibrator to comply with best practice. The instrument also has six selectable setups – four that are pre-defined to legislative standards and two that can be customised so that you get the data you need. Regardless of the setup, the CEL-62x measures and stores ALL parameters, even if not selected and these can be viewed in the software (sold separatly). All runs are date and time stamped and the CEL-62x stores up to 100 runs. Simply connect your CEL-62x to a PC via the USB connection and the data can be easily reviewed without the need for proprietary software (sold separatly).The instrument has a single large measurement range of 20-140dB meaning that you don't need to change range.Features:Compact, rugged designSimple operationSingle large measurement rangeLarge memoryHigh resolution colour displaySimultaneous measurement of all workplace noise parametersInstrument menu in 9 languagesPre-defined and user configurations availableAutomatic calibration functionHigh Resolution Colour DisplayThe 62X series uses colours of the high-resolution display to aid the user in making measurements. Measurement screens are colour coded depending on the mode of operation. For example, during a measurement run, the header and footer of the display is green, whereas when a run is stopped they are red, similar to traffic lights for ‘stop' and ‘go'. Measured parameters are displayed in different colours, and the bar graphs are illustrated with the same colours to give an easy understanding of the noise climate.Unique colour coding of measurementsBright backlightApplications:Occupational Noise MeasurementWorkplace noise according to ISO9612 and OSHA 29CFR 1910.95Selection of hearing protectionCalculation of noise exposureEnsuring compliance with workplace noise legislationMachinery noise testsSimple OperationThe 62x 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, available in seven languages.The instrument has six selectable set-ups. Four pre-defined setups can be used to satisfy local workplace noise legislation. Two user set-ups can be defined to display parameters and weightings as required. Regardless of the setup used, the 62x series measures and stores all parameters and weightings even if not selected. These can be viewed if necessary on the software (sold separatly).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 series acts like a memory card, so data files can be moved to a PC and easily reviewed without the need for proprietary software (sold separatly).Intuitive menu structureMultilingual user interfacePredefined and user selectable set-upsDigital TechnologyBy using Digital Signal Processing (DSP) technology, the 62x series measures all the workplace noise parameters simultaneously with necessary time and frequency weightings, preventing incorrect setup of the instrument. The instrument has a single large measurement range of 20-140dB, eliminating the need to change measurement range and preventing errors.On the CEL-620B model, octave analysis is performed in realtime, saving time compared to performing measurements sequentially.Octave band results are shown in both bar-graph and tabular form with the dominant frequency highlighted. Time history of the broadband noise level is displayed in real-time, so a user can see how the noise level varies with timeLarge measurement rangeSimultaneous measurementAutomatic calibration.
