Brief introduction:
AWA5688 multifunctional sound level meter is a new generation of noise measuring instrument adopting digital signal processing technology. It is an upgraded AWA5680 series product with lower power consumption, stronger function, color LCD screen, friendly interface and rich display content. The frequency meter weight of A, C and Z and the time meter weight of F, S and I can be used for integral measurement, statistical analysis and 1/1oct analysis at the same time. Users can also customize 1/3oct analysis, FFT analysis, personal sound exposure measurement, recording and other functions as required. The instrument can be widely used in environmental protection, labor health, industrial enterprises, scientific research and teaching and other fields.
