Sound Examiner SE-401 TSI

Sound Examiner SE-401 TSI

Model Number: SE-402-AC3 – High-Performance Sound Level Meter for Occupational and Environmental Applications

Sound Examiner SE-401 TSI is part of the SE-400 Series of precision sound level meters designed for accurate noise measurement in dynamic environments. Whether used in industrial, environmental, or occupational settings, the SE-401 offers reliable performance, capturing detailed sound level data over time to support regulatory compliance and safety programs.

This Class 1 sound level meter delivers high-accuracy readings and conforms to international standards (IEC 61672-1, ANSI S1.43). The SE-401 features a removable preamplifier, allowing remote microphone placement for applications requiring discreet or distant monitoring. With built-in data logging and DMS software compatibility, users can analyze time-stamped results, identify patterns, and create detailed reports. Its aerodynamic body minimizes interference, and its intuitive interface requires no setup, making it ideal for quick deployment.

The SE-401 is ideal for professionals conducting occupational noise evaluations, environmental impact assessments, machinery noise studies, and general acoustic measurements in demanding conditions. Optional intrinsically safe models (SE-401-IS and SE-402-IS) enable safe use in hazardous environments.
