SVAN 979 is a device combining all necessary measurement functionalities in one hand-held tool. The instrument is dedicated for acoustic engineering applications such as sound insulation measurements, precise frequency or signal tonality analysis. In standard, this sophisticated tool has been equipped with frequency analysis in 1/1 & 1/3 octave bands, FFT analysis and audio recording for noise source recognition.

Basic kit also includes building acoustic pack: RT 60 measurement and signal generator functions.

New generation sound level meters

The new SV 973 class 2 sound level meter, and the SV 971A class 1 sound level meter are two new generation models that comply with IEC 61672. They have a small size and weight as well as improved application compatibility via mobile apps, which is their main feature.
