The SE-402 sound level meter kit(SE-402-AC3)is engineered to accurately measure noise levels in highly variable environments. It capable of computing the average sound pressure over a length of time and log the data at user defined intervals to help in the assessment of occupational and environmental noise levels. Also, the sound patrol feature allows for portable printing in the field providing documentation of the measured results.
This SE-402-AC3 kit includes the sound meter, class 2 microphone, USB cable, USB power cable, windscreen, calibrator adapter, and storage case.
