The CRY3016 is a portable Class 1 acoustic calibrator designed for high-precision calibration and verification of sound level meters, measurement microphones, and acoustic measurement chains in both field and laboratory environments. It supports one calibration frequency, 1000 Hz, and provides two selectable sound pressure levels, 94 dB and 114 dB. In high ambient noise conditions, the higher output level can be used to reduce the influence of background noise. Equipped with an integrated sound pressure feedback loop and real-time compensation for temperature, humidity, and barometric pressure, the CRY3018 effectively minimizes drift caused by environmental changes, ensuring stable output and reliable calibration performance under a wide range of operating conditions.
