TM
Sound Examiner SE-400 Series are sound level meters used to measure noise over time with robust
logging capabilities, selective measurement values, and with a variety of end-user applications including
occupational noise measurements and assessment of environmental noise levels.
Models and options
There are five models offered in the Sound Examiner Series including intrinsically safe (IS) and non-intrinsically safe
models. The differences between models are accounted for by three primary characteristics: intrinsic safety,
accuracy of measurement, and remote microphone measurement capability. The table below summarizes the
differences between the models.
