Sound Examiner SE-402 TSI

Sound Examiner SE-402 TSI

Model Number: SE-402-AC3

The Sound Examiner SE-402 is a robust, easy-to-use sound level meter from the Quest™ SE-400 Series by TSI. Designed for measuring noise levels in variable environments, the SE-402 helps users assess both occupational and environmental noise exposure accurately. With Class/Type 2 accuracy and onboard data logging, this instrument is well-suited for professionals needing reliable noise data to support compliance and analysis.

Featuring advanced digital technology, the SE-402 calculates average sound pressure levels (Leq and Lavg) over time, capturing essential metrics for workplace safety assessments and environmental monitoring. The SE-402 does not include a removable preamp like other models, making it a more streamlined and affordable choice for general-duty applications that don’t require remote monitoring.

Its simple interface and aerodynamic body enable quick setup-free deployment, while compatibility with Quest Detection Management Software (DMS) allows users to visualize and report results efficiently. Ideal for walkthrough surveys, acoustic studies, and machine noise analysis, the SE-402 is a dependable tool in any noise monitoring program.
