Acoustic Calibrators SV 34A, SV 33A, SV 36

Is my result correct?

The only way to be sure that you can answer ‘yes’ to this questions is to perform an acoustic calibration. Standards impose the requirement to calibrate the measurement channel before each measurement or measurement session and after the measurement as well for result verification purposes.

If you don’t perform these basics checks then what do your results actually mean?

SV 36

SV 36 Class 1 acoustic calibrator features an OPTIC SENSOR that detects microphone presence and turns on/off the calibrator automatically.

The SV 36 acoustic calibrator is a small, portable dual-range Class 1 device (sound source). Powered by two AAA batteries, it contains a loudspeaker producing acoustic pressure of defined level 94 db & 114 dB at frequency of 1 kHz.

SVANTEK Calibrators are based on the reference sensors and microprocessor controlled signal source including digital SOUND PRESSURE LEVEL, STATIC PRESSURE and TEMPERATURE compensation.

Unlike many others, the SVANTEK calibrators feature a ROBUST HOUSING that gives the comfort of a secure grip to the user.

The accuracy of acoustic calibrator should match the class of the sound level meter. A CLASS 1 (SV 33A or SV 36) or CLASS 2 (SV 34A) calibrator should be used, depending on the class of instrument.

The user interface of the calibrator is equipped with a PUSH BUTTON and a LED diodes signalizing calibration and battery faults.

SV 33A

SV 33A Class 1 Acoustic Calibrator is suitable for calibration of Class 1 and Class 2 sound level meters and dosimeters with 1/2 microphones.

SV 34A

SV 34A Class 2 Acoustic Calibrator generates reference signal of 114 dB at 1 kHz and is designed to calibrate Class 2 sound level meters and noise dosimeters with1/2 microphones.

Thanks to the MEMS technology the calibrator presents the best price versus performance ration in a current noise market.
