Acoustic calibrator
The CEL-120 helps users achieve highly accurate calibration of sound level meters in the field and is fully compliant with IEC 60942:2003 and ANSI S1.40:2006 standards. It features a simple keypad specially designed for intuitive control. A micro electrical-mechanical system microphone and digital feedback loop maintain the acoustic pressure in the cavity at the required level.
