Sound Examiner Sound Level Meter

Sound Examiner Sound Level Meters Overview

Sound Examiner™ SE-400 series of sound meters are engineered to accurately measure noise levels in highly variable environments. These easy-to-use detection instruments calculate the average sound pressure level (LEQ/LAVG) over the run time; data log the maximum, minimum and peak values, and enable data to be downloaded for further analysis.

Some models have Class/Type 1 or Class/Type 2 microphones; SE-401 and SE-402-R include removable preamps for environmental noise applications.

On-board data logging allows user to capture maximum, minimum and peak values for thorough analysis.
Optional SoundPatrol portable digital printing enables hard-copy documentation of measurement results in the field
User can specify microphone type (Class/Type I or Class/Type II) based on application.
