The Model 9104 Digital Sound Level Meter identifies the source of dangerously loud noise. Sound decibels are measured and displayed on a large LCD. An “F/S” response time button provides a choice of slow response measurements for measuring stable noise or fast for varying noise. A “Max Hold” setting measures the maximum noise level of sounds and updates continuously if a louder sound is detected.
