Sound Level Meter and Spectrum Analyser

Class 1 Sound Level Meter expandable to 1/3-octave band spectrum analyser

  • Class 1 sound level meter
  • USB and RS-232 communication ports
  • Real time spectrum analysis in 1/3-octave bands (Optional)
  • Reverberation time measurement (Optional)
  • Measures all parameters simultaneously with A, C & Z frequency-weightings
  • One single range

Main Features

The SC310 is a user-friendly, type 1 integrating sound level meter. It can be used as either a sound level meter or as a real time spectrum analyser for both 1/3-octave bands and whole octave bands - with Type 1 filters.

The SC310 measures all functions simultaneously, with all frequency-weightings. Amongst these are all the functions necessary to calculate the basic indices for the acoustic evaluation of most countries in the world: S, F and I functions, equivalent continuous levels, percentiles, impulsiveness indices, peak levels, sound exposure levels, short functions, etc.

Thanks to its modular platform, the SC310 can be expanded with advanced measurement options, such as 1/3-octave band spectrum analysis, FFT analysis or reverberation time measurement.

The free memory space can be also configured as a circular memory. This feature along with the possibility of downloading data simultaneously to its storage, converts the SC310 into the perfect platform for permanent acoustic monitoring.

The SC310 preamplifier and microphone are detachable. You can uncouple the microphone and move it away from the SC310 by using the extension cable (CNR-010). The instrument can be complemented with an outdoor kit (TK-1000) for making measurements in the open air.

PC Software

CESVA Capture Studio

CAPTURE Studio is a comprehensive software application that allows you to: configure all the parameters of the instrument on just one screen, retrieve & display data from the instrument in real time (increasing the capacity of the registers because it is limited by the available memory of the PC), download registers from the instrument memory to a PC, erase the instrument memory (so the instrument will be empty & so you will have the full capacity to save the new measurements), display the data files graphically and numerically, convert them into different formats (.txt, .xls, .mdb), copy the graphic and numeric information supplied by the software (to create personalized reports) and save the files in its own *.ccf format (which then cannot be changed and guarantees their total integrity and legality).

CAPTURE Studio provides you with a convenient, easy-to-use environment for obtaining digital data acquired by the instrument.

CAPTURE Studio has been designed as a work environment for the new range of CESVA products. Software available for Cesva sound level meters, vibrometers and dosimeters.
