Casella CEL-620B Integrating Octave Band Sound Level Meter Kit (Class 2)
The CEL-600 series sound level meters give high standards of performance never seen in such as compact design using the latest digital technology. Depending on user requirements, there are different models available for use in general workplace sound level measurement. The instruments are suitable for applications such as selection of hearing protection, calculation of noise exposure, ensuring compliance with workplace noise legislation or machinery noise tests.
High Resolution Colour Display
A high resolution colour TFT display and bright backlight is used in the instruments to allow it to be seen in all light conditions. Casella sound level meters also use unique colour coding of measurements, 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.
Sound level measurement is made easier through an intuitive menu structure with no need for a manual and a multilingual user interface. Available in seven languages, a simple icon structure is used with word prompts for each selection. The instrument has six selectable setups. Four pre-defined setups can be used to satisfy local workplace noise legislation. Two user setups can be defined to display parameters and weightings as required. The CEL-600 series measures and stores all parameters and weightings even if they are not selected and regardless of the setup used.
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, sound level meter acts like a memory card, so data files can be moved to a PC and easily reviewed without the need for proprietary software.
This Casella sound level meter has a large measurement range of 20-140dB and is able to use Digital Signal Processing (DPS) technology to measure all the workplace noise parameters simultaneously with necessary time and frequency weightings, preventing incorrect setup of the instrument.
Octave analysis is performed on the 620B model in real-time which saves time compared to performing measurements sequentially. Results from this can be shown in both bar-graph and tabular form with the dominant frequency highlighted.
Within the CEL-600 series there are models CEL-610, CEL-620A and CEL-620B, each with different functions. The CEL-610 measures instantaneous and maximum sound pressure levels, the CEL-620 measures average noise levels as well as peak levels and the CEL-620A model also simultaneously measure LC and LA used within the HML method for the selection of hearing protection. In addition, the CEL-620B model performs real-time octave band analysis from 16Hz to 16kHz, values which are used in the octave band method for selection of hearing protection. If future requirements Automatic calibration changes, any instrument can be upgraded to a higher model without returning to Casella. Complete measurement kits are provided with an acoustic calibrator in a robust kit case complete with instruction manuals and calibration certificates.
