Lar Wall-Mount Digital Sound Level Meter — LCD Decibel Monitor 30~130dB with Adjustable Alarm

Compact wall-mount sound level meter from Lar with a clear LCD that displays numeric readings for easy viewing. No setup is required — the unit is ready to use as soon as it powers on. Measurement range: 30 ~ 130dB, with configurable upper and lower limit alarms to notify you of out-of-range levels. The alarm duration can be set between 5~120 seconds (factory default: 120 seconds). A built-in buzzer sounds when the real time measurement reaches the alarm threshold; the reading is held for 5s before the meter returns to normal monitoring mode.
