This is a high-precision
sound level meter that provides analog signal output
and measures sound pressure level with measuring accuracy
up to ±2dB. It features a wide measuring range
of 40 ~ 130 dB, Bar-Graph Indication, A/C
frequency weighting, Fast / Slow response and Maximum
Hold function. The meter also provides a windscreen
to filter-out unwanted signals. In addition, it has Software CD and USB cable which
can be used as Data Logger to record Noise Data into your
PC or Laptop via the USB port. With USB cable attached to
the port of the meter and the Software installed to your
PC/Laptop, you can view the online test, real time data
measurement curve diagram and data input/output and the
curve of the noise maps. You can also save and print for
later comparison.
Sound level meter can be used for noise
projects, quality control, environmental noise control and
health monitoring such as: construction, schools, hospitals,
shopping malls, theaters, offices, road traffic, family,
audio and other occasions, the noise level measurement applications.
This meter meets the International Committee
of the IEC651 TYPE2 and the American National Standards
ANSIS1.4 TYPE2 as well as the measurement requirements of
Safety Engineers, Health, Industrial Safety Offices and
Sound Quality control in various environment.
