Is your classroom too loud? The Chatter Tracker will help you to keep the noise down. Using a traffic light method, the lights move from green to amber to red as the sound level increases. When the light turns red a siren indicates that the noise is too loud - the siren stops when the noise in the room drops.
Operates on 240v transformed to 12v.
