A handy, portable sound source for calibration of sound level meters and other sound measurement equipment. The calibrator is very robust and stable, and conforms to EN/IEC 60942 Class LS and Class 1, and ANSI S1.40-1984.

For maximum confidence in your measurement results you can quickly compensate for local measurement conditions by calibrating before every measurement. Twin sound pressure levels guarantee definitive checks even in noisy environments, and ensure linearity in your microphones.
