Nor1255 is a small battery-operated precision class 1 microphone calibrator generating 114 dB @ 1k Hz conforming to IEC 60942 and ANSI S1.40. Each Nor1255 sound calibrator is supplied with an individual accredited calibration certificate.
The all-digital design with a quartz-controlled signal generator ensuring a frequency stability not yet seen on any calibrator on the market today. The reference microphone and accompanying control circuit maintain a constant sound pressure level inside the calibration coupler and automatically adjusts for changes in load volume, temperature, humidity and barometric pressure.
