Digital Sound Noise Level 40-130 DB Meter Measure Decibel

• This product is high precision instruments that measures sound pressure level with measurement accuracy up to ± 2dB commonly used in noise pollution studies for the quantification of almost any noise, but especially for industrial and environmental. It can be used as Data Recorder Noise Data Disk in your PC or Laptop via USB port. With the cable plugged into the USB port of the meter and CD Software Installed to your PC / Laptop, you can see the online test, real-time data measurement curve diagram and input / output data and the curve of the noise cards. you can also save and print for later comparison.
• With wide measuring range (40 ~ 130dB), Bar-Graph Indication, A / C Frequency weighting, Fast / Slow response and Maximum Hold function. the meter also provides a windshield to filter-unwanted signals. In addition, the counter meets the IEC651 TYPE2 International Committee and the American National Standards ANSIS1.4 TYPE2 as well as the measurement requirements of Safety Engineers, Health, Offices and Sound Quality Control in various Industrial Safety environment.
• Sound meter can be used for noise projects, quality control, outdoor noise limitation and health monitoring such: construction, schools, hospitals, shopping malls, theaters, offices, road traffic, family, audio and other occasions , the measurement of noise level applications. The meter has wide range of applications such as sound pollution studies, research and other industrial uses.
