Description
Sound level monitoring is essential to determine what protective measures are required for employees who are routinely exposed to loud noise. Perform noise surveys in compliance with OSHA, MSHA, DOD, ACGIH, and ISO standards with the Extech SL400 dosimeter. An SL400 noise accumulation survey can determine total sound exposure over an 8-hour period. This compact, lightweight dosimeter can also serve as a sound level meter, logging up to 999,999 readings with sampling times between 1 second and 24 hours. An optional 94 dB calibrator allows you to perform before-and-after calibration checks, per ANSI standards. The SL400 comes with PC software to control setup and retrieve stored events or analyze real-time measurements.
