Description

SC-1 ACOUSTICAL CALIBRATOR INCLUDING CA-1/2″ & CA-1/4″ ADAPTER

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 carrying 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.
