Main Features
Colour Touch Screen
The SC250 has a colour touch screen to manage the complete equipment. Its capacitive screen is 3.5” size, it helps to any action will be very fast and intuitive. The screen of the SC250 shows a clear and sharp view even in broad daylight; it also lights up automatically when the sound level meter is turned on.
Single Measuring Range
The SC250 has a single measurement range, from 16.5 dBA to 140.1 dBC peak. This fact saves time since it is not necessary to configure the equipment previously. It also avoids having to repeat measurements due to measuring out range.
Sound level meter expandable to 1/3 Octave
The SC250 is expandable through FR250* module, this activates the spectral analysis by
octave band (1/1) and third octave band (1/3). Performing frequency analysis increases the applications that can be evaluated with the SC250, such as tonal components, low frequency or acoustic absorption of materials.
Wireless sound level meter: Bluetooth / WiFi
The SC250 has internal Bluetooth® communication to connect it to a device (Tablet, mobile,…)
and thus to be able to operate the SC250 remotely using the SC250 Link+ App from CESVA. The WIFI communication of the SC250 allows to send the memories to the CESVACloud+ server this means to have the memories immediately from anywhere. It also allows to update the firmware version and activate the modules purchased, only by connecting the sound level meter to internet.
(+) process
Built-in memory with CSV Files
The SC250 has internal memory to store the recordings made and final results. In addition
to the history of date and time changes, sensitivity adjustment and firmware version. These data are saved in csv files and can be opened from different operating systems as Microsoft Windows®, Mac OS® or LINUX®. The SC250 csv files are compatible with the CESVA Lab application.
NC/NR curves and backerase
The SC250 evaluates the spectrum according the NC (Noise Criterion) and NR (Noise Reduction) curves families, this feature allows the equipment to carry out the evaluation of background noise in rooms. With the BACKERASE option, allows the SC250 to eliminate unwanted audible events corresponding to the last 10 seconds before a pause.
Modules
FR250 - 1/3 and 1/1 OCTAVE FILTERS
What does it measure?
8 Hz to 16 kHz octave bands filters analysis and 6.3 Hz to 20 kHz 1/3-octave band filters analysis, plus overall functions.
Applications
- Assessment of environmental noise (Corrections for the presence of tonal and impulsive components and low frequency content)
- Hearing protection selection (by octaves)
- Noise evaluation of air conditioning equipment
- Measurement of the sound level of technical equipment in buildings (ISO 16032)
- Industrial noise analysis of machinery (development, quality control and maintenance)

The SC250 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. |
|
|
|
|
|
Download and configureCESVA Lab is cost free and gives you a simple way to download all the information from the SC250 by simply removing the microSD card and post-process it. It also allows you configuring the SC250 from the PC.

View and ListenMoreover, 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.

Edit and re-calculateIf 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. |
