PRODUCT DATASHEET SL400 Personal Noise Dosimeter 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. Applications: - Personal accumulated noise exposure measurement - Workplace noise assessment - OSHA and other regulatory agency compliances Features • • Measures frequency weighted noise exposure and • One user-defined measurement setup peak (C, Z) sound level • Optional 94dB calibrator to perform “before” and “after” calibration checks per ANSI standards Datalogs up to 999,999 readings when used as a sound level meter with sampling times between • software to control setup and retrieve stored events or 1 second and 24 hours • analyze real-time measurements Sound level mode: displays sound level, min/max, time-averaged sound level (Leq), peak, and sound • USB interface with Windows® 7 and 8 compatible • Complete with belt clip, clip-on 0.5" (12.7mm) exposure level (SEL) microphone with 32" (81.3cm) cable and windscreen, Adjustable Criterion Level, Exchange Rate, & Threshold 9V battery, software, USB cable, and carrying case Specifications Standards IEC61252-1993, IEC67672-1-2003, ANSI S1.25-1992, ANSI S1.4-1983, ANSI S1.43-1997 Ranges (Accuracy) 30 to 90 dB, 50 to 110dB; C, Z Peak: 70 to 140dB / C and Z Peak: 90 to 143dB (Accuracy: ±1.4dB@94dB 1kHz) Frequency Weighting A, C, Z Response Rate Fast, Slow, Impulse Bandwidth 20Hz to 8kHz Memory Dose: 10,000 points/SLM: 999,999 points Criterion Level / Threshold Level 30 to 140dB in 0.1dB steps / 30 to 140dB in 0.1dB steps Exchange Rate 3, 4, 5 or 6 dB Measurement Duration 5, 10, 15, or 30 minutes; 1, 2, 4, 8, 10, 12, or 24 hours Measurement Modes %Dose, Lxmax, Lxyp, Lxmin, Lxeq, SEL (LAE), PeakMAX, LAVG, TWA, LEP, LN% SPL, Lxmax, Lxyp, Lxmin, Lxeq, SEL (LAE) PeakMAX Dimensions/Weight 4.2 x 2.6 x 1.3” (107 x 65 x 33mm) - exclude connector on top/ 7oz.
