Extech SL130G Sound Level Alert With Alarm (Discontinued by Manufacturer)

The SL130G is a sound level alert with alarm for continuous monitoring of sound levels. Ideal for industrial, hospital, auditoriums, schools and other areas where there is a need for being alerted when sound level reaches set points. You can set the SL130 so the RED LEDs flash when the sound level is below the"LO" set point where people in the audience may not be able to hear. When the sound level is above the "LO" set point, the GREEN LEDs indicate the sound level is acceptable.
