Sound Calibrator Nor1256 | Norsonic

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. In addition the sound calibrator measures the environmental conditions; air pressure, temperature and humidity.
