Specifications

• Personal noise dosimeter for OSHA and IEC noise accumulation surveys, determining total sound exposure over an 8-hour period
• Applications: personal accumulated noise exposure, workplace noise assessment, sporting events, construction, regulatory compliance
• Measures frequency-weighted noise exposure and peak (C, Z) sound level
• Sound level mode shows sound level, min/max, time-averaged level (Leq), peak and sound exposure level (SEL)
• Datalogs up to 999,999 readings in sound level meter mode, with sampling times from 1 second to 24 hours
• Adjustable criterion level, exchange rate and threshold; one user-defined measurement setup
• USB interface with Windows-compatible software to set up the unit, retrieve stored events or analyze real-time measurements
• Optional 94 dB calibrator for before and after calibration checks per ANSI standards
• Standards: IEC61252-1993, IEC67672-1-2003, ANSI S1.25-1992, ANSI S1.4-1983, ANSI S1.43-1997
• Ranges: 30 to 90 dB, 50 to 110 dB; C, Z peak 70 to 140 dB and 90 to 143 dB
• Accuracy: ±1.4 dB at 94 dB, 1 kHz
• Frequency weighting: A, C, Z; response fast, slow, impulse; bandwidth 20 Hz to 8 kHz
• Memory: dose 10,000 points; sound level meter 999,999 points
• Criterion and threshold level: 30 to 140 dB in 0.1 dB 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
