The Extech SL130 Sound Level Monitor with Display and Alarm is ideal for monitoring of noise levels in buildings, offices, production plants, etc. The SL-130 has an adjustable alarm function, so it can adhere to the legal level checks and if necessary protective measures can be taken. The SL-130 is also ideally suited as a control instrument at lectures or performances. When sound level of the lecture is optimal, the LED's are green, if you go over or under the desired sound level then they either light up or blink red and signal to the lecturer to adjust the sound level.
