Sound Level Meter LMSN-A100 is an instrument that measures the exponential time-weighted sound level. Features a ½ inch electret condenser microphone and offers the measurement of 4 parameters. It allows for option A, C, and F weighting, Fast/Slow reaction times, and an interface that connects to a PC using RS-232 data output. It is a compact, lightweight, and portable device designed for simplified operation.
