Sound Calibrator

The SV 36 Class 1 Acoustic Calibrator is a precision reference sound source designed for accurate calibration and verification of sound level meters and acoustic measurement systems. This equipment generates a stable acoustic signal at precisely controlled sound pressure level, typically 94 dB or 114 dB at 1000 Hz frequency, conforming to IEC 60942 Class 1 specifications. The calibrator features microphone coupling chamber, crystal-controlled frequency stability, and battery-powered operation for fiel
