EXTECH Noise Dosimeter Personal SL400-NIST

Benefits

• 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.

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 and Threshold
• One user defined measurement setup
• Optional 94dB calibrator to perform before and after calibration checks per ANSI standards
• USB interface with Windows compatible software to control setup and retrieve stored events or analyze real time measurements
• Complete with belt clip, clip on 0.5 inch (12.7mm) microphone with 32 inch (81.3cm) cable and windscreen, 9V battery, software, USB cable, and carrying case
