- SV 35 & SV 33 class 1 sound calibrators meeting IEC 60942:2003 - SV 34 class 2 sound calibrator meeting IEC 60942:2003 - Frequency 1 kHz ? - 94 dB or 114 dB levels (SV 35) - 114 dB level (SV 33, SV 34) - Built-in reference microphone SV 35 Class 1 Acoustic Calibrator produces an acoustic pressure of defined level 94 db & 114 dB at frequency of 1 kHz.
SV 35 Class 1 Acoustic Calibrator produces an acoustic pressure of defined level 94 db & 114 dB at frequency of 1 kHz. The SV 35 is suitable for calibration of Class 1 and Class 2 sound level meters and dosimeters with 1/2 microphones. Unlike many others, the Svantek calibrators feature a robust housing that gives the comfort of a secure grip to the user. The interior design of our acoustic calibrators is based on the reference microphone and microprocessor controlled signal source including digital static pressure and temperature compensation.
