The SC-1 sound calibrator is a single-frequency dual-amplitude,self contained field calibrator used to quickly and precisely verify the accuracy and the sensitivity of microphones.
The unit generates a 1kHz reference tone at 94 and 110 dB SPL. The SC-1 consists of a amplitude switchable constant frequency oscillator, a transducer and a microphone coupler. The coupler accepts a large variety of microphones.
Including CA-1/2" og CA-1/4" adapter.
