Digital sound pressure level meter 30~130 db decibel bp
This Digital Sound Level Meter (SL-824) is an instrument to measure Sound Pressure Level in decibels (dB). SL-824 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.
SL-824 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.
