Sound Level Meter and Analyzer [SoundPro DL]

The SoundPro™ DL`s powerful feature set makes it easy to document and analyze noise exposures. This hand-held instrument includes two virtual sound level meters to take full or third octave band real-time measurements while simultaneously measuring broadband sound and features time history data logging with 1 second to 60 minute intervals.

 

Comprehensive

  • Accurately measures, documents and displays noise exposures to support hearing conservation
  • 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

 

Intuitive

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

 

Powerful

  • Available in Class/Type 1 and Class/Type 2 models to accommodate application-specific analysis
  • Removable SD memory card plus optional data logging for enhanced post-processing and analysis
  • Compatible with 3MTM Detection Management Software DMS (optional) for advanced reporting and analysis
