Extech SL400 Personal Noise Dosimeter with USB Interface, 143 dB, 8 kHz

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.

Features:

• Measures frequency weighted noise exposure and peak (C, Z) sound level
• Datalogs up to 999,999 readings when used as a sound level meter with sampling times between 1 second and 24 hours
• Sound level mode: displays sound level, min/max, time-averaged sound level (Leq), peak, and sound exposure level (SEL)
• Adjustable Criterion Level, Exchange Rate, & Threshold
• One user-defined measurement setup
• Optional 94dB calibrator to perform "before" and "after" calibration checks per ANSI standards
• USB interface with Windows® 7 and 8 compatible software to control setup and retrieve stored events or analyze real-time measurements
