Product details
Introduction to AWA5688 Multi functional Sound Level Meter:
AWA5688 Multi functional Sound Level MeterIt is a new generation noise measurement instrument that adopts digital signal processing technology. It is an upgraded product of the AWA5680 series, with lower power consumption, stronger functions, color screen LCD, user-friendly interface, and rich display content. A. The three parallel (simultaneous) frequency weights of C and Z, as well as the three parallel (simultaneous) time weights of F, S, and I, can be used for simultaneous integration measurement, statistical analysis, and 1/1 OCT analysis. Users can also customize functions such as 1/3 OCT analysis, FFT analysis, personal sound exposure measurement, recording, etc. according to their needs. This instrument can be widely used in fields such as environmental protection, labor hygiene, industrial enterprises, scientific research and teaching.
