Extech SL400 Personal Noise Dosimeter with USB Features

• The Extech SL400 measures frequency weighted noise exposure and peak sound level. It displays sound level, min/max, time-averaged sound level (Leq), peak, and sound exposure level (SEL).

• The 407744 Sound Calibrator generates a 1kHz sine wave at 94dB to calibrate and verify sound level meter operation with Total Harmonic Distortion (THD) <2%.

• The SL400 datalogs up to 999,999 readings with adjustable Criterion Level, Exchange Rate and Threshold.

• The 407744 calibrator includes battery test position to check battery status and meets IEC standard 60942 1997-11.

• The SL400 dosimeter bundle includes 0.5" (12.7mm) microphone with 32" (81.3cm) cable, windscreen, software, USB cable and carrying case.

About Extech SL400 Personal Noise Dosimeter With USB

Extech SL400 Personal Noise Dosimeter with USB Interface The SL400 is a Personal Noise Dosimeter with USB Interface. For employees that are exposed to loud noise, sound level monitoring is essential to determine what protective measures are required. Perform OSHA and IEC Noise accumulation surveys to determine total sound exposure over an 8-hour period. The SL400 is a compact, lightweight Dosimeter with USB interface designed to test noise exposure and provide noise surveys for compliance with OSHA, MSHA, DOD, ACGIH, and ISO standards. Includes PC software to control setup and retrieve stored events or analyze real-time measurements. Complete with belt clip, clip-on 0.5" (12.7mm) microphone with 32" (81.3cm) cable and windscreen, 9V battery, software, USB cable, and carrying case.
