SC160 

Integrating Sound Level Meter   

Real time frequency Analyser* in Octave Band

 

The 

SC160

  is  a  user-friendly,  low  cost,  class  2  integrating 

sound  level  meter  and  real  time  octave  band  spectrum  ana-
lyser*  that  allows  you  to  make  sound  measurements  quickly, 
conveniently  and  easily.  It  has  a  single  range,  so  there  is  no 
need to make any range adjustments. 

The 

SC160

 simultaneously measures all the functions for each 

function mode (sound level meter or spectrum analyser*) with 
A,  C,  and  Z  frequency  weightings  .  The 

SC160

’s  graphic 

screen provides graphical and numerical representation of the 
functions measured.  

The data measured and recorded by the 

SC160

 

can be trans-

ferred  to  a  personal  computer  so  that  they  are  available  in 
electronic  format.  The  AC  output  allows  you  to 
obtain  the  signal  from  the  preamplifier  and 
make a calibrated recording on D.A.T.

 

  

The microphone  is  detachable.  It can therefore 
be uncoupled and moved away from the 

SC160

 

by means of an extension cable (CNR-ITV).  

The 

SC160

 can be used as either a sound level 

meter  or  a  spectrum  analyser*  and  room 
noise evaluator by NC and NR curves. 

The  sound  level  meter  mode  is  ideal  for 
measuring  overall  sound  pressure  lev-
els. The 

SC160

 simultaneously meas-

ures  all  functions  with  all  frequency 
weightings  and  calculates  statistical 
data  as  maximum  and  minimum  val-
ues and percentiles. 

The spectrum analyser* mode allows 
you  simultaneously  and  in  real  time 
to  measure  the  sound  levels  and 
peak  levels  for  octave  bands  from 
31,5  Hz  to  16  kHz  and  the  overall 
sound  pressure  levels  and  peak  lev-
els A, C and Z with frequency weight-
ings. 

Within  the  analyser*  mode  there  is  a 
special  screen  to  evaluate  room  noi-
se,  especially  designed  for  HVAC 
system  installers,  engineers,  and 
consultants,  that  allows  you  to  asses 
noise  in  real  time  using  the  NC  and 
NR curves criterion.
