TSI – Quest Sound Examiner 400 Series

The TSI / Quest Sound Examiner Sound Level Meter SE-402 IS is an intrinsically safe meter engineered to accurately measure noise levels in highly variable environments. This easy-to-use instrument calculates the average sound pressure level (LEQ/LAVG) over the run time; data log the maximum, minimum, and peak values, and enables data to be downloaded for further analysis.
