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 an amplitude-switchable constant frequency oscillator, a transducer and a microphone coupler. The coupler accepts a large variety of microphones.
Rational offers this unit pre-packaged in a protective case with both the 1/2" and 1/4" adapters as well as with operating instructions and factory certified calibration chart. The calibrator uses a single 9 Volt battery (included).
NOTE: The Rational RTA420 requires the 10mm calibrator adapter for use with the SC-1.
