- RION Sound Calibrator NC-75
Compact and lightweight sound calibrator allows highly reliable and accurate measurement anywhere
■ Integrated newly developed reference microphone enables feedback control that completely eliminates the need for atmospheric pressure and coupler volume correction, resulting in highly accurate and reliable calibration.
■ Effective coupler sound insulation (30 dB or higher*) Permits calibration also in relatively noisy environments.
*A-weighted sound level insulation performance measured with pink noise
■ Each product comes standard with a JCSS Calibration Certificate, demonstrating high quality.
