SV 33

Class 1 noise calibrator

The SV 33  is a Class 1, single level acoustic calibrator designed to calibrate Class 1 sound level meters with 1/2″ microphones. It is built into a robust housing which gives a comfortable and secure grip to the operator.

Like other SVANTEK acoustic calibrators, the SV 33 does not require manual adjustments as it automatically compensates for any temperature and humidity changes.

It uses the latest in MEMS technology which gives the very best price to performance ratio currently available on the acoustic market.
