Ensure your noise measurements are compliant with our dual-level acoustic calibrator. You can calibrate both sound level meters and noise dosimeters at both 94dB and 114dB at 1kHz with one instrument!

• IEC 60942: 2017 Class 1 or Class 2 performance
• Dual-level 94dB and 114dB @ 1kHz sound pressure level outputs
• Suitable for use with a standard 1/2″ microphone capsule
• Ideal for sound level meters and noise dosimeters

The Dual-level Acoustic Calibrator

Class 1 and Class 2 Dual-level Acoustic Calibrators

Our dual-level acoustic calibrator (sound calibrator) is suitable for the field and laboratory calibration of sound level meters, noise dosimeters, and other noise measurement instruments.

The calibrator is simple to operate and meets the requirements of the latest IEC 60942:2017 standard for acoustic calibrators with performance to Class 1 or Class 2 and features both 94dB and 114dB at 1kHz sound pressure level output in one single instrument.

It’s ideal for use with a variety of noise dosimeters, where 94dB or 114dB can be used in preference.
