Rion NC-75 is a compact and lightweight sound calibrator which 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.
Each product comes standard with a JCSS Calibration Certificate, demonstrating high quality.
The NC-75 features an integral reference mic and feedback system which automatically compensates for atmospheric conditions and the load volume of the microphone making ideal not only for Rion microphones/sound level meters but any manufacturer’s microphones as long as they meet the size specifications set out in IEC 61094-4.
The Rion NC-75 can be used with 1/2″ and 1″ microphones and can also support 1/4″ microphones when used with an optional adaptor.
With at least 30 dB (A) of acoustic isolation, the NC-75 can be used in noisy environments and has a battery life in excess of 50 hours.
