Digital Sound Level Meter - 30-130 Dba, 35-130 Dbc | 5-digit Lcd Display, Built-in Bar Graph, Ac/dc Output Options

SLE-834
The Sound Level Meter is used to measure sound level in decibels (dB). An output port on the meter records sound level data. A switch on the meter is used to select dBA or dBC weighting. The Sound Level Meter also has an LCD panel, which allows you to use it as a stand-alone device. A dB range switch and a response switch provide flexibility in the standalone mode.
