3M Sound Examiner SE-400 Series Sound Level Meters

3M™ Sound Examiner SE-400 Series Sound Meters

The Sound Examiner SE-400 series of sound meters are engineered to accurately measure noise levels in highly variable environments. These easy-to-use 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.

Occupational Assesment Made Easy

Intuitive User Interface

With the SE-400's intuitive user interface you are only one press away from taking your acoustic measurements. Measurement parameters include SPL,Lavg/Leq, Min, Max, and Peak. These rugged, high-quality instruments meet applicable accuracy and performance requirements for sound level meters as defined by ANSI S1.4, ANSI S1.42, IEC 61672, IEC 61010, and IEC 61000-4.

The easy to use SoundPartrol portal digital printing capability included on the SE 401 with Class/Type 1 or SE-402 Class/Type2 models requires minimal training, so it can be easily deployed in the field by law enforcement personnel. Includes I/O and serial printing connector.

Data Logging

Variable, user-selectable data logging intervals. Stored session summary data includes: LEQ/LAVG, LMax, LMin, LPk(peak), and user settings. Use 3M(TM) Detection Management Software (DMS) to export, report and share data from the SE-400 series of sound meters.
