Sound Calibrator [NC-75]

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

 

Features

• Integrated newly developed reference microphone enables feedback control that completely eliminates the need for atmospheric pressure and coupler volume compensation, resulting in highly accurate and reliable calibration.
• Effective coupler sound insulation (30 dB or higher*) permits calibration also in relatively noisy environments.

*A-weighed sound level insulation performance measured with pink noise

• Each product comes standard with a JCSS Calibration Certificate, demonstrating high quality.
• Conforming with IEC 60942: 2003 class 1 and JIS C 1515: 2004 (Also complies with IEC 60942 Version 4 currently under revision)
• Supports calibration of RION sound level meters compliant with IEC 61672-1: 2013, JIS C 1509-1: 2005 and JIS C 1516: 2014.
• Supports calibration of RION microphones and microphones of other manufacturers meeting the size specifications of IEC 61094-4.
• Supports 1-inch, 1/2-inch, and 1/4-inch microphones (1/4 inch with optional adapter)
