The NA-27 is a compact and eminently
portable unit that allows real-time 1/1-octave and 1/3-octave analysis
without requiring external accessories. Being able to perform quick and precise
1/3-octave analysis in the field is an advantage
that will be appreciated by researchers and scientists anywhere. During measurement,
the user can switch between 1/1-octave, 1/3-octave, and noise level analysis, as
well as between numeric and graphical indication at
the simple touch of a key.
