Extech Sound Level Meter SL130W K

Ideal for monitoring noise levels in buildings, offices, production facilities, etc. The SL-130 features an adjustable alarm function, allowing for the verification of compliance with legal levels and the implementation of protective measures if necessary. The SL-130 is also perfect as a control instrument during speeches or presentations. When the speaking volume is optimal, the LEDs light up green. If the desired volume is exceeded or not reached, they light up or blink red, signaling the speaker to adjust the volume. The alarm is indicated visually by super-bright LEDs that are visible from up to 30 meters or via an analog switching output.
