?Accurate/Fast Measurement?The MAX mode of the decibel meter displays the maximum/minimum value of the sound in the area, and the real-time monitoring function provides you with real-time data of the sound level in the area. The decibel meter also has a fast and slow response speed conversion function, and the detection error is only 1.5dB. The fast response is 0.0125/s, which is suitable for ordinary environment measurement. The slow response is 0.1/s, which is used for environmental measurement with relatively large noise level changes. ?A/C Weighted Measurement Method? A weighted simulates the frequency characteristics of low-intensity human ear noise, which is suitable for the detection of environmental noise. C weighted simulates the frequency characteristics of high-intensity human ear noise, which is suitable for the sound pressure analysis of machine motors and machines. Professional decibel meter, more professional measurement method to provide users with a more perfect use experience. ?Dual Unit Switching? The sound level meter has two new measurement units: SONE/dB. The SONE mode is commonly used to detect the sound of musical instruments and the volume of performances, which is closer to the volume heard by the human ear. The dB mode is used for environmental noise detection in factories and homes, with a standard decibel range. At the same time, the decibel meter is also equipped with a windproof ball to reduce the noise caused by wind resistance. ?Humanized Function? DURFICST decibel meter uses a three-color display to display volume changes. The screen functions include: battery reminder, volume detection, and different detection modes. The radio equipment is: 1/2-inch condenser microphone, and the detection is more professional. The decibel meter adopts a new mold one-piece molding process, with soft silicone on both sides, ergonomic design, making you feel more comfortable when using it. ?Convenient and Lightweight? The decibel meter is lightweight and weighs only 205g. The product comes with a cloth bag for easy storage and carrying. DURFICST sound level meter is widely used for sound quality testing in factories, transportation, cars, baby rooms, sound system offices, as well as homes, schools and construction sites.
