The Sound Examiner will measure noise levels in highly variable environments, with intrinsically safe (IS) versions available for monitoring in hazardous areas. These meters compute average sound pressure level (LEQ/LAVG) over the run time, helping you to assess occupational and environmental noise levels more accurately.

Instruments are available in Class/Type 1 and Class/Type 2 models. The SE-401 and SE-402-R models feature a removable preamp to support remote monitoring. All models are ready to use with no set-up required.

TSI Quest Sound Examiner SE-400 Sound Level Meters are an excellent solution for a variety of applications, including:

  • Occupational noise evaluation including hazardous locations
  • Environmental noise assessments
  • General acoustic analysis
  • Machinery and equipment noise evaluations
