The SV 36 is a high-precision Class 1 acoustic calibrator designed for laboratory and field verification of sound level meters and microphones. Compliant with IEC 60942 standards, it delivers stable and accurate calibration signals at 94 dB and 114 dB, ensuring traceable reference levels for professional acoustic measurements.
Engineered for demanding measurement environments, the SV 36 offers low harmonic distortion, fast level stabilisation, and reliable performance across a wide range of environmental conditions. Its compatibility with 1/2” and 1/4” microphones makes it an ideal choice for calibration tasks where accuracy, repeatability, and compliance are critical.
