iSEMcon SC-1 Acoustical Calibrator

The SC-1 sound calibrator is a one frequency dual amplitude,self contained field calibrator that quickly and also precisely verifies the accuracy and the sensitivity of microphones. The unit generates a 1kHz reference tone at 94 and 110 dB SPL. The calibrator uses a single 9 Volt battery. The SC-1 consists of an amplitude switchable constant frequency oscillator, a transducer and a microphone coupler. The coupler accepts a large variety of microphones. Comes with CA-1/2" & CA-1/4" adapters
