Class 1 Sound Calibrator ST-120 Image

The ST-120 Sound Level Calibrator is used for the calibration of the pressure sensitivity of the microphone and sound level measuring equipment. ST-120 conforms to the standard of IEC60942 (2003) Class1. The design of ST-120is based on a feedback arrangement to ensure a high stable sound pressure level. The performance is very stable; it does not required for the revision to the microphone equivalent volume.
