The sound sensor consists of a measuring microphone with handle and a wall holder with 1.5 m cable, a noise transmitter and a digital display. The main application of the noise meter is the continuous noise measurement and noise monitoring of factory halls, production rooms and large events (discotheques, folk festivals, kart tracks, etc.). The digital display has a relay output for the control of alarm horns or blinkers for visual or acoustic warning and a control output.
