The SC420 is an instrument distinguished for its power, versatility, ergonomics and its high performance as a class 1 sound level meter, according to IEC 61672. Thanks to its modular platform, the SC420 can be expanded with advanced measurement options, such as third octave band spectrum analysis, FFT analysis or reverberation time measurement.
 
The SC420 provides audio recording with prerecording and voice comments, external memory through microSD cards, automatic start and stop of measurements and audio recordings based on timers and thresholds, and has been designed according to the philosophy in order to offer a simple and enjoyable experience for the user from the start.

Optional Module Extensions (please ask for pricing):
TF420: Spectrum analyser module in 1/3 octave bands from 10 Hz to 20 kHz and overall functions
OF420:  Spectrum analyser module in 1/1 octave bands from 16 Hz to 16 kHz, overall functions and NC and NR curves
RT420: 1/1 and 1/3 octave band reverberation time module by interrupted noise and integrated impulse response methods. Includes parameters to evaluate the non linearity of the curves and filters influence
