The SL130W 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. You can reverse the Red and Green LEDs activation per user color preference.
