 Calibration can be performed automatically with just a simple operation.

 

About Calibrator NC-75

 

Compact and lightweight sound calibrator allows highly reliable and accurate measurement anywhere.

Integrated newly developed reference microphones 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.
