What are the functions of the AWA6021A/L sound level meter calibrator

The AWA6021A/L sound calibrator adopts acoustic negative feedback technology, which ensures a very stable sound pressure level and does not require correction for temperature and atmospheric pressure changes. There are two sound pressure levels of 94 dB and 114 dB, with small size, light weight, stable performance, and easy use. The performance meets the technical requirements of GB/T 15173-2010/IEC 60942:2017 for Level 1 sound calibrators and can be used for Level 1 and Level 2 sound pressure level calibration of sound level meters.
