 This Professional Digital Sound Level Meter is an instrument to measure Sound Pressure Level in decibels (dB). Unlike with traditional Sound Level Meter, this unit can be used as Data Logger to record Noise Data into PC through USB. It has Real-Time Data Sampling Analysis and record up to 131070 Noise Data. These recorded data can be plotted in Graph.
The device is featured with wide measuring range (30 ~ 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. Moreover, it has Date and Time function. The DC power can be provided by USB cable when connecting to PC.

This device is a portable, easy to use and handy instrument for sound quality control in office, home, school and construction site. The meter has wide range of applications such as noise pollution studies, research and other industrial use.
