SV - Model 102 -Single or Dual Channel Noise Dosimeter
Noise Dosimeter for Workplace Safety, Occupational Health and Industry. SV 102 dual-channel instrument presents completely new approach to occupational health and safety acoustic monitoring task. The binaural dose measurement and 1/1 octave analysis are simultaneously performed. Octave analysis providing direct data for ear-protectors designing together with Audio Events Recording function show new reference standard available in compact size instrument.

The SV 102 is offered with one or two dedicated SV 25D ceramic microphones assembled in 1/2” very robust housing enabling an easy calibration by direct usage of common acoustic calibrators. Microphone can be attached in extremely short distance to the human ear using special mounting clip and dedicated headband. Moreover, SV 25D offers function of automatic calibration thanks to build-in TEDS (Transducer Electronic Data Sheet).
SV 25S, the smart sensor with TEDS, has been developed for measurements under headphones or earmuffs (Hearing Protection Device - HPD) using the MIRE technique (Microphone In Real Ear). With special adapter this microphone can be also calibrated with available acoustic calibrators.
SV 102, together with SV 25S, are designed for individual real-world test of the earmuffs noise reduction ratio.
SV 102 can be also used as a dual-channel type 2 sound level meter and real-time 1/1 or 1/3 octave analyser. Three acoustic profiles per channel allow parallel measurements with independently defined filters and RMS detector time-constants. Advanced time-history logging for each profile, together with spectra saving and Audio Events Recording provide complete information about measured signal, which is saved in nonvolatile internal memory up to 64 MB. Data files are easily downloaded to any PC using USB interface and SvanPC+ software.
Instrument is powered from two AA standard or rechargeable batteries (separate charger is required) as well as the USB interface.
