Integrating sound level meter SC-202
The integrating sound level meter Class 2 SC-202 is expandable to an octave band and third octave band spectrum analyser which measures all parameters simultaneously with all frequency and time weightings in the various time bases without the need for configuration.
This model of sound level meter has a removable pre-amplifier for both vehicle and machine noise measurements (sound pressure and sound power).
It not only carries out the measurements, but also the checks and calculations indicated in the standards, in order to obtain the final result on site.
