Pressure 30~130 dB Decibel Noise Measurement Sound Level Meter

Specifications

Brief Description

This digital sound level meter is an instrument to measure Sound Pressure Level in decibels (dB). This meter is featured with wide measuring range (30 ~ 130 dB), bar graph indication, A/C frequency weighting, Fast / Slow modes and maximum hold function. The meter also comes with a windscreen to filter-out unwanted signals in the presence of wind.

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