Sound Level Meter (Intrinsically Safe) [SE-401-IS]

The Sound Level Meter SE-401-IS is engineered to accurately measure noise levels in highly variable environments. These advanced instruments compute the average sound pressure level (LEQ/LAVG) over the run time and feature user-selectable data logging intervals, helping you to more accurately assess occupational and environmental noise levels.

 

Certified

• SE-401-IS has Intrinsic Safety approvals

 

User Friendly

• Intuitive interface allows for out-of-box use with little to no training
• User selectable data logging intervals for download and analysis with 3MTM Detection Management Software (sold separately)
• Averaging functionality allows for easy measurement in variable environments

 

Versatile

• Printing capability with optional digital printer provides hard copy documentation in the field
• Choose from models with Class/Type 1 or Class/Type 2 microphones, dependent on your application

 

Accurate

• Meets applicable industry standards
• Useful tool as part of a Hearing Conservation Program; be confident that data collected is accurate
