3M SE-400 Sound Examiner Sound Level Meters

Keison Products are proud to introduce the 3M SE-400 Sound Examiner Sound Level Meter range.

The Red models within this range have certified and Intrinsic Safety approvals.

The intuitive interface allows for an out-of-box use with little or no training. User selectable data logging intervals allows for download and analysis with a 3M Detection Management Software (sold separately).

Averaging functionality allows for easy measurement in variable environments making it extremely versatile.

With an optional digital printer its unfaltering printing capabilities provides hard copy documentation in the field.

Options provided to choose from models with Class/Type 1 or Class/Type 2 microphones, depending on the necessity and application. SE-401 and SE-402-R are models that include removable preamp.

Reliable and accurate, this unit meets applicable industry standards. A very useful tool as part of a Hearing Conservation Program - you are guaranteed of accurate data collected.
