Nor1256 Sound Calibrator

The Nor1256 is an advanced multi-level, multi-frequency Class 1 sound calibrator featuring automatic barometric pressure compensation and integrated environmental sensors for precision calibration under varying atmospheric conditions. Compliant with IEC 60942 Class 1 and type approved by PTB (Germany), BEV (Austria), and METAS (Switzerland), the Nor1256 delivers certified output levels at both 94 dB and 114 dB, at both 250 Hz and 1000 Hz frequencies, with ± 0.2 dB accuracy. The built-in barometric pressure, temperature, and humidity sensors automatically compensate for atmospheric effects on the acoustic output, ensuring accurate calibration at any altitude or under changing weather conditions. This is particularly valuable for field measurements in the GCC where temperature extremes and varying atmospheric pressure can affect calibration accuracy. The OLED display shows the actual compensated output level along with real-time environmental readings, giving operators full confidence in their calibration reference. The multi-frequency capability distinguishes the Nor1256 from single-frequency calibrators. By providing verified output at both 250 Hz and 1000 Hz, engineers can check the frequency response of their measurement system at two widely separated frequencies, confirming proper operation across the measurement bandwidth. For calibration laboratories, research institutions, and professional acoustics consultants requiring the highest level of field calibration traceability, the Nor1256 represents the most advanced handheld sound calibrator available.
