Integrating Sound level meter class 1 with audio recording expandable to spectrum analyzer for third octave bands
The ON&PLAY philosophy has been developed to be intuitive - getting first time users up & running quickly & providing a stress-free return to measurements, even after long periods of inactivity.
ON&PLAY offers a simple and enjoyable experience from the first moment of contact with the device.
With ON&PLAY, measurement has never been so easy.
The information measured by the SC420 (final results and time histories), audio files and voice notes are saved on the MicroSD card inserted into the SC420.
Once the measurements are complete and the SC420 is powered-off, the MicroSD card can be removed and inserted into a computer. The data can then be transferred using the program 'Memory Download' - the download can be completed much faster this way.
MicroSD cards up to 32 GB have been tested successfully.
The SC420 is an instrument that stands out for its power, versatility & ergonomics. It delivers high performance as a Class 1 integrating sound level meter (in accordance with IEC 61672, ANSI S1.4 and ANSI S1.43).
Thanks to its modular platform, the SC420 can be expanded with advanced measurement options such as 1/3-octave band spectrum analysis, FFT analysis and reverberation time measurement.
The SC420 has a complete system of automated parameters, such as starting & stopping measurement and audio recording. Automatic timers and triggers are also available when exceeding threshold by DEN time-zones .
Its power and versatility offer infinite combinations which will provide optimal performance for even the most demanding of users.
The SC420 is designed to work as an automatic continuous noise monitoring unit. An environmental monitoring powering option is available, which allows measurements to be resumed after recovery from a power failure.
Optimal file structuring allows efficient data transfer & manipulation; this includes downloading while measuring and erasing parts that have already been downloaded.
The SC420 can record audio files (listening quality), whilst it logs acoustic functions, facilitating its subjective evaluation and the recognition of sound sources.
The SC420 communicates with a PC through a USB port and through Class 1 wireless Bluetooth® communication, in order to download & manipulate data, as well as allowing external control and real time visualization.
With the Back erase function, the SC420 can delete the last 10 seconds of the measurement
in progress. This option is ideal when unwanted noise events occur during measurement.
Occupational noise mode simultaneously measures all the parameters necessary to evaluate the noise exposure of the worker with and without hearing protectors (SNR, HML and Octaves).
16 Hz to 16 kHz octave band filters analysis plus overall functions and NC and NR curves
10 Hz to 20 kHz 1/3-octave band filters analysis plus overall functions
Reverberation time measurement by 1/1 and 1/3-octave bands using the interrupted noise and the integrated impulse response methods. Includes parameters for the evaluation of non-linear decay curves and the influence of the filters
FFT Analysis of 10000 lines from 0 to 20000 Hz (2 Hz/line)
Records WAV (uncompressed) format audio files, 24 bits resolution, 48 kHz sampling frequency and constant gain for later analysis
Available on Google Play for free. SC420 Link is a mobile application designed for Android. Thanks to its intuitive operation, the user can take measurements with the SC420 sound level meter from the touch screen of a smartphone and configure its measurement parameters remotely.
The connection of the SC420 Link application with the SC420 is done through Bluetooth and allows full control of the sound level meter: Change of measurement mode, start and stop of measurement, pause, backerase and start of audio recording.
SC420 Link allows to display in real time the graphic and numerical information of the measurement modules of the SC420: Sound level meter, Spectrum analyser 1/1*, Spectrum analyser 1/3* and Noise at work*.
*Optional modules
Simply mount the SC420 sound level meter on a tripod at the measurement point, position yourself at a suitable distance, connect it to your smartphone via Bluetooth and start measuring remotely safe from potentially dangerous environments and without interfering with measurement in sensitive environments.
The SC420 sound level meter measures a lot of functions for very long periods of time and also records audio files automatically. The best way to approach the analysis of all these functions together with the qualitative information provided by the audio files is to use the CESVA Lab software application.
CESVA Lab is cost free and gives you a simple way to download all the information from the SC420.
Moreover, it provides an intuitive and user-friendly interface which allows numerically and graphically display of all the measurement information on the screen in several synchronized panels (spectrum and time history graphs and 3D spectrograms) and listen to the audio files for each sound event.
CESVA Lab allows you to copy any table or graph from the screen to the clipboard to be able to paste it into any text editor. In addition, simply by pressing a button, you create a PDF report with all the information of the selected instant, personalized with your own annotations. It also allows you to work with spreadsheets. CESVA Lab always exports with the same format, this allows you to create your own spreadsheets templates and reports.
If what you want is to recalculate a section, simply select it, add it to a layer and simply calculate. Different layers, containing several sections, can be calculated simultaneously. Each layer is calculated and saved in a separate file.
The Result Merging Tools (SE003) brings together the final results of multiple measurements in a single file (. csv). It is a practical and simple software that, together with the CESVA sound level meters, becomes the perfect solution for all types of measurement campaigns.
Groups the final results of several measurements in a single csv file. Select the folder where the measurements you want to group are located, select the measurements, the functions and the frequency weighting that you want to appear in the resulting csv file. Click the button to create the csv final file. This will appear automatically in the same folder where we had the initial measurements. The csv final file will contain the final results of the measurements we had selected. The Result Merging Tools (RMT) merges, in a single file (. csv), the final results of different measurements carried out with the SC250/SC202 or SC420 sound level meters. This software allows you to customize the resulting file to fit the user's needs. Result Merging Tools (RMT) is characterized by its simplicity of use and compatibility with most applications. In addition to saving work time, it eliminates errors made when grouping results manually. In a few seconds the user will obtain a file with the final results of all measurements.
