Decibel Meter, Digital Sound Level Meter 30 130dBA, GR 882A SPL Handheld Volume Tester with Backlight LCD Display, Audio Noise for Classroom, Home, Office, Factory

🔊Accurate measurement: The Decibel Meter measurement range of the sound level meter is 30dB to 130dB. This Digital Sound Level Meter is a high-precision sound level meter wIth an accuracy of ± 1.5dB. Resolution 0.1 dB. The frequency range is 31.5Hz-8.5KHz. Real time measurement of sound level can provide you with accurate data for daily use. 🔊A/C weighted measurement: Decibel Meter noise level meter has two evaluation modes: A and C. A-weighted simulation of the frequency characteristics of low intensity human ear noise is applicable to the detection of environmental noise. C-weighting simulates the frequency characteristics of high-intensity noise in human ears, and this Digital Sound Level Meter suitable for analyzing industrial noise, such as machine motors. 🔊Fast and slow measurement: The Decibel Meter has a fast/slow reaction rate selection function. For general environmental measurements, the fast response rate uses a time constant of 0.125 s/time. The slow response rate uses 1s/time constant, which is used for environmental measurement with large change of noise level. 🔊Big LCD display:The Decibel Meter is a 5-bit LCD display with a resolution of 0.1 dB and a sampling rate of 2 times per second. The large backlight LCD digital display makes the reading effect clearer in the dark. It has low battery level display and overload indication "OVER" and "UNDER" symbols. 🔊Convenient and light: The GOYERRNES Decibel Meter size is 8.7×2.6×1.3in (220×67×32mm), the weight is 0.46lb (210g), the structure is exquisite, and it is easy to carry. It can be used for noise engineering, quality control, health prevention and various environmental noise measurements. For example, noise measurement applications in factories, offices, roads, homes, stereos, etc., Manufacturer: GOYERRNES
