Nor1256 is a small battery-operated precision class 1 microphone calibrator conforming to IEC60942 and ANSI S1.40. The combination of two different levels and two different frequencies allow both level linearity and frequency linearity to be verified.
Acoustic Precision Calibrators
The robust and handy acoustic calibrators are available in 2 versions with varying degrees of accuracy. The class 1 calibrator Nor1251 is applied most frequently and Nor1253 is mainly suited for laboratory use.
