Sound level meter and spectrum analyser

Integrating Sound level meter class 2 with touch screen expandable to spectrum analyzer for octave and third octave bands

  • Capacitive colour touch screen
  • Built-in memory with CSV Files
  • Backerase of the last 10 seconds
  • USB-C connectivity, Bluetooth® integrated and WIFI communication
  • Ready for Apps for mobile or Tablet (Android)
  • Expandable to spectrum analyzer for octave and third octave bands

Main Features

Colour Touch Screen

The SC202 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 SC202 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 SC202 has a single measurement range, from 30.5 dBA to 140.0 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 SC202 is expandable through FR202* 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 SC202, such as tonal components, low frequency or acoustic absorption of materials.

Wireless sound level meter: Bluetooth / WiFi

The SC202 has internal Bluetooth® communication to connect it to a device (Tablet, mobile,…)
and thus to be able to operate the SC202 remotely using the SC202 Link+ App from CESVA. The WIFI communication of the SC202 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.

Built-in memory with CSV Files

The SC202 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 SC202 csv files are compatible with the CESVA Lab application.

NC/NR curves and backerase

The SC202 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 SC202 to eliminate unwanted audible events corresponding to the last 10 seconds before a pause.


Numerically displays three functions (F1, F2, and F3). This screen allows modifying the function to be displayed regardless of the status (play, rec, pause or stop).


It shows the temporal evolution and the value of the functions (F1, F2, and F3), graphically represents the last 60 measured values.


Pass / Not pass

It graphically displays the values ​​of the F1 function together with the threshold level. And represents in red the values ​​that exceed the threshold level. The threshold level can be modified at any time.

Optional Modules

FR202 - 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.


  • Hearing protection selection (by octaves) 
  • Noise evaluation of air conditioning equipment
  • Industrial noise analysis of machinery (development, quality control and maintenance)
  • Assessment of environmental noise (class 2) (Corrections for the presence of tonal and impulsive components and low frequency content)
