SV 34B Calibrators

The SV 34B is a Class 2 sound calibrator engineered to generate a stable 114 dB sinusoidal reference signal at 1 kHz for calibrating 1/2-inch microphone-based instruments. It features a microprocessor-controlled feedback loop that continuously monitors the output via a built-in piezoresistive reference sensor and automatically compensates for changes in atmospheric pressure and temperature. This ensures calibration accuracy is maintained across varying field conditions, making it suitable for both laboratory and on-site use. Its robust housing provides a secure grip and durability for demanding measurement environments. The SV 34B is compatible with sound level meters and noise dosimeters conforming to Class 2 requirements.
