HY603 sound calibrator

1. Performance

　　The HY603 sound calibrator meets the requirements of the national standard GB/T15173-2010 and the international standard IEC 60942:2003 "Electroacoustic Sound Calibrator" for level 2 sound calibrators. It is suitable for calibrating noise measuring instruments such as microphones with nominal diameters of 23.77 mm, 12.7 mm, and 6.35mm, and sound level meters. HY603 can generate two nominal sound pressure levels of 94 dB and 114 dB. In addition to calibrating the overall sensitivity of the noise measuring instrument, it can also roughly check the linearity of the instrument and the error of the level range controller, which helps to detect faults and defects in the instrument.
