Model
820
There
exists a need to select an instrument that will do just what
you need it to do. The 820 was designed with this
in mind. The Model 820 is
the perfect environmental noise analyzer, maintaining all of
the features of the 812 but with added memory, modem
capability, daily and exceedance histories.
The1/2"
condenser microphones used with our Model 820 allow
for a wider dynamic range and greater level of accuracy. The
Models 812 and 820 meet the IEC and ANSI requirements for
Type 1, Precision Integrating Sound Level Meters.
Fundamental to each of these instruments is an integrating
sound level meter. Each features true RMS and dual Peak
detectors that operate simultaneously. Each has Slow, Fast,
and Impulse detector rates. Each has A and C frequency
weighting filters.
