KEY STRENGTHS:
This is high-precision sound level meter provides analog signal output and measures sound pressure level with measuring accuracy up to±2dB commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial and environmental.
Featuring wide measuring range (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, the 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.
Plus, it has an optional Software CD and USB cable (not included in the set) 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. The meter has wide range of applications such as noise pollution studies, research and other industrial use.
