Model 812
There
exists a need to select an instrument that will do just what
you need it to do. The 812 was designed with this in mind.
For example, a consultant that works heavily in the
industrial hygiene sector will greatly benefit from having
the Model 812, a hand held data logging integrating sound
level meter and a personal noise dosimeter.
The
condenser microphones used with our Model 812 allows
for a wider dynamic range and greater level of accuracy. The
Models 812 meets 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.
