Sound Level Meter Portable Noise Decibel Measuring Accurate A Weighted for Home Construction Sites ZL-81A

1、REAL TIME ACCURATE MEASUREMENT: The MAXimum mode of the decibel meter displays the maximum or minimum sound value in the area, and the real time monitoring function provides you with real time data on the sound level in the area 

2、ADJUSTABLE RESPONSE SPEED: The decibel meter also has the function of fast and slow response speed conversion, and the detection error is only ±2dB. Fast response 125ms, suitable for ordinary environmental measurement. Slow response 1sec for environmental measurements with relatively large noise level changes 

3、APPLICABLE SCENARIO: The A weighted of sound level meter simulates the frequency characteristics of low strength human ear noise, which is suitable for the detection of environmental noise 

4、NOISE REDUCTION: Used for factory and home environmental noise detection, with standard decibel range. At the same time, the decibel meter is also equipped with a windproof ball to reduce the noise caused by wind resistor 

5、WIDE APPLICATION: Sound level meter is widely used in factory, traffic, automobile, baby room and other places of sound quality test, very versatile
