The Extech SL130 Sound Level Alert with Alarm is a sound level detector and alarm device that can be used in industrial, hospital, auditorium, school and other places where it is necessary to be alerted when sound level reaches set point.
The EXTECH SL130G is a sound level alert designed for industrial, hospital, auditorium, and classroom environments. It features built-in LEDs that alert users when sound levels exceed a high set point or fall below a low set point, with visibility from up to 30 meters (100 feet). The device allows user-settable high or low limits ranging from 80 to 130 dB and includes an output to drive an external relay module.
