Sound Level Meter (Wireless Capability Available)

  • Features


The SoundPro™ SE/DL series provides advanced sound level monitoring and comprehensive data analysis. Available in Class 1 and Class 2 models, these instruments feature large screen displays that enable real-time frequency analysis and data storing capabilities. Octave band analysis enables environmental noise monitoring, noise enforcement, and noise control evaluation.







  • ​Accurately measures, documents and displays noise exposures to support hearing conversation
  • Measures against multiple sound level meter standards simultaneously with two virtual meters
  • Octave band analysis capability enables environmental noise monitoring, noise enforcement, and noise control evaluation




  • ​Large displays with menu-driven interface and quick keypad calibration




  • ​Available in Class/ Type 1 and Class/ Type 2 models to accomodate application-specific analysis

  • Removable SD memory card plus optional data logging for enganced post-processing and analysis

  • Compatible with 3M Detection Management Software DMS (optional) for advanced reporting and analysis

3M Detection Software (DMS)      


Designed for dosimetry, sound level measurements, heat stress assessments and environmental monitoring, this advanced software helps safety and occupational professionals:


  • Configure instrumentation and save pre configured setups
  • Retrieve, download, share and panels to intuitively interpret your measurements
  • Create charts, tables and panels to intuitively interpret your measurements 
  • Generate insightful charts and reports
  • Export and share recorded results


The software integrates with 3M™ Detection Solutions data logging instruments and will help you improve both operating efficiency and reporting in acoustics, heat stress and encironmental monitoring.
