Applications
Use the SV 34B for pre- and post-survey checks of Class 2 sound level meters and personal noise dosimeters in occupational and environmental noise work.
SV 34B or SV 36?
SV 34B is intended for Class 2 calibration at 114 dB. Choose SV 36 when your team needs Class 1 calibrator performance, both 94 dB and 114 dB levels, 1/4-inch microphone compatibility or broader professional instrument coverage.
What it solves
It provides a current practical reference source for checking Class 2 instruments before and after measurements, supporting more reliable field workflows.
