    Acoustic calibrator for Class 2 sound level meters with 1/2" microphone

    • A simple keypad for intuitive operation and adjustment of calibration level
    • MEMS microphone and digital feedback loop for maintaining acoustic pressure
    • IEC60942 Class 2
    • Microprocessor detects when the microphone is removed
    • Low battery consumption provides up to 2 years of operation

    Calibration of a sound level meter before and after each measurement sequence is an important procedure when performing noise measurements. Calibration ensures that instruments always provide accurate measurements, for noise monitoring that helps ensure compliance with occupational and environmental noise regulations.

    The CEL-120 calibrator is therefore designed to comply with legislation according to IEC 60942 2003 and ANSI S1.40 2006. These standards specify precise calibration over a wide range of temperature, humidity, and pressure conditions typical for fieldwork, helping to ensure accurate calibration under all conditions.

    The CEL-120 is compact, ergonomically designed, and simple to use.
