ZLLJYBLG GL81A Decibel Meter, 30-130dB Digital Sound Level Meter with A-Weighted, Fast/Slow Response, Max/Min Hold, Backlit Display, Noise Tester for Home, Work, Factory, Classroom（Red）

Decibel meters use precise capacitive microphones to capture sound. It is equipped with A-weighted facilities that can measure noise levels ranging from 30 to 130 dB with an accuracy of 1.5 dB and a frequency of 30 to 8000Hz. It is very suitable for monitoring noise levels in communities, home theaters, sound systems, cars, workshops, schools, offices, factories, transportation, and construction sites

• Wide & Accurate Measurement Range：Measure sound levels from 30dB to 130dB with 2dB accuracy, ideal for testing home noise, industrialequipment, classroom environments, and more. Features A-weighting for human ear-friendly readings, soyou get real-world relevant data.
• Fast/Slow Response & Max/Min Function：Switch between FAST (8 measurements/sec) and SLOW (1 measurement/sec) response modes to capture sudden noise spikes or average levels. The MAX/MIN function records peak and lowest values, perfect for tracking fluctuating noise over time.
• Fast/Slow Response & Max/Min Function：Switch between FAST (8 measurements/sec) and SLOW (1 measurement/sec) response modes to capture sudden noise spikes or average levels. The MAX/MIN function records peak and lowest values, perfect for tracking fluctuating noise over time.
• Clear Backlit Display & Data Hold：Green backlit screen ensures visibility even in low-light conditions. Press the HOLD button to lock readings instantly, so you can easily note down measurements without rushing. The simulation strip also provides intuitive visual feedback.
• Easy to Use and Fully Functional: Anti slip design, portable noise meter is easy to carry. A decibel meter is a battery powered noise meter equipped with two durable batteries and automatic power-off function, which can extend battery life. When the battery level is low, a low battery indicator light will appear on the screen to remind users to replace the battery in a timely manner
