For measuring total sound exposure over an 8-hour period
Personal Noise Dosimeter
Features:
Perform OSHA and IEC Noise accumulation surveys
One user-defined measurement setup
Adjustable Criterion Level, Exchange Rate, and Threshold
Applications include Personal accumulated noise exposure 
measurement, Workplace noise assessment, OSHA and 
other regulatory agency compliances
Measures frequency weighted noise exposure and peak sound
level simultaneously
Datalogs up to 12,000 readings when used as a sound level
meter with sampling times between 1sec and 1hr
In sound level mode, meter displays sound level, time-averaged
sound level (Leq), peak, and sound exposure level (SEL)
Optional 94/114dB calibrator to perform “before” and 
“after” calibration checks per ANSI standards
Stores up to 20 dosimeter surveys. 
Data includes Start/Stop Time, %Dose, %Dose projected for an
8 hour period, and peak level when used in the Dosimeter mode
