CA111 is a small sound source for calibration of measurement microphones, sound level meters and other sound measurement equipment. The calibrator can be used on 1/2-inch and 1/4-inch microphones with adapter. It conforms to IEC 60942:2003 Class 1, ANSI S1.40-1984 and GB/T 15173-1994. and has dual 94 & 114 dB sound pressure level outputs.

CA114/CA115 has the similar structure to that of CA111. It conforms to IEC 60942:2003 Class 2, ANSI S1.40-1984 and GB/T 15173-1994. and has 94/114 dB sound pressure level outputs.
