Moobody Wall-Mount Digital Sound Level Meter Decibel Tester 30 ~ 130dB

Moobody wall-mounted digital sound level meter features a large LCD that shows clear numerical readings for quick, at-a-glance monitoring. The unit is plug-and-play with no configuration needed—simply power on and begin measuring. It covers a measurement range of 30 ~ 130dB and provides both upper and lower limit alarms. The alarm duration can be set between 5~120 seconds (factory default: 120 seconds). An audible alarm output (buzzer) sounds when live levels cross the set threshold; the device holds the triggered reading for 5s before returning to normal monitoring mode.
