Descrição de Digital Noise Volume Measuring Meter, Wall Mounted Sound Level Meter with Large LCD Screen

This instrument is mainly used for environmental noise measurement, noise suppression engineering monitoring, quality control, health protection monitoring, and similar applications. It is widely used in factories, offices, audio-visual venues, transportation routes, homes, engineering construction sites, and other places that require noise monitoring and control.

It features a large digital LCD display with clear numerical readings, so the measured value can be checked at a glance. No setup is required, and it can be used immediately after powering on, making daily noise checking straightforward and efficient.

The measurement range is 30 to 130 dB, with upper and lower limit alarms for practical monitoring. The alarm time can be adjusted from 5 to 120 seconds, with a factory default of 120 seconds. When the real-time measurement reaches the alarm level, the unit outputs an audible warning, holds the data for 5 seconds, and then returns to normal mode.

Designed for flexible placement, it includes hanging holes for wall mounting. It is suitable for checking and monitoring sound levels in personal, family, business, study, and industrial environments, offering broad usability across different spaces that need sound level awareness.
