digital

SV 102A+ Class 1 Dual Channel Dosimeter is presenting new approach to occupational health and safety acoustic monitoring task. This dosimeter can be also used as a dual-channel Class1 sound level meter and real-time 1/1 octave & 1/3 octave analyser. Octave analysis, providing direct data for the design of the ear-protectors, together with Audio Events Recording (AER) function show the new reference standard on acoustic dose measurement field. The binaural dose measurement and octave analysis are simultaneously performed by this compact-size instrument. Three acoustic profiles per channel allow parallel measurements with independently defined filters and RMS detector time constants. Advanced time-history logging in each profile, together with spectra saving and Audio Events Recording provide a complete information about the measured signal. Data is stored in large 8 GB memory and can be easily downloaded to any PC using USB interface and Supervisor software. The small and compact SV 15 preamplifier together with special mounting clip and dedicated headband enables an easy attachment of the microphone in extremely short distance to human ears. Calibration by measurement can be easily performed by direct usage of common acoustic calibrators.
