Specification Brand : Generic BulletPoint1 : High Precise Sensor: The decibel meter is made of high-precision chip, which has a wide measuring range of 30-130dB and a high accuracy of ±1.5dB. Built-in capacitive microphone sensor, wide sound collection range, strong anti-interference ability, high sensitivity and accuracy. BulletPoint2 : Fast and Slow Measurement: The sound level meter has the function of converting the fast and slow response rate. The fast response rate uses a time constant of 125ms/time for general environmental measurement. The slow response rate uses a 1s/time constant, which is used for environmental measurements with relatively large changes in noise levels. BulletPoint3 : Multi-field Applications: The dB meter is A-weighted, which is suitable for the measurement of environmental noise, such as traffic noise, baby room noise, classroom noise, home theater noise, industrial noise, workshops noise, office areas noise, and so forth. BulletPoint4 : Multifunction Design: It can measure and record the maximum and minimum values, and has the function of automatic shutdown without operation for 10 minutes and low battery indication, which is convenient and practical to use. The sound level meter is equipped with LCD digital screen with backlight, which is convenient for data reading. BulletPoint5 : Windproof Sponge Design: The microphone is designed with a windproof sponge, more accurate sound collection, filtering the impact of wind on the sound.
