CRY3018 Sound Calibrator
The CRY3018 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 two calibration frequencies, 250 Hz and 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.
Product Highlights
Sound Pressure Feedback System with Environmental Compensation
The CRY3018 incorporates an integrated sound pressure feedback loop together with intelligent compensation based on temperature, humidity, and barometric pressure sensing. This design automatically corrects for the effects of environmental fluctuations, reducing drift and measurement error while maintaining a consistent calibration sound pressure level and enhanced repeatability across a wide range of test conditions.
Dual-Frequency and Dual-SPL Verification
The CRY3018 supports two calibration frequencies, 250 Hz and 1000 Hz, as well as two selectable sound pressure levels, 94 dB and 114 dB. This enables users to choose the most appropriate combination based on the characteristics of the device under test and the ambient noise conditions, allowing for more comprehensive pre- and post-test verification as well as improved measurement consistency validation.
USB-C Fast Charging with Pass-Through Operation
The CRY3018 supports USB-C fast charging, allowing its internal battery to be fully recharged in approximately 2 hours, which is well suited for a full day of field use. It also supports pass-through operation while charging, significantly reducing downtime during extended tasks and improving overall efficiency for continuous operation.
High-Brightness OLED Display
The high-contrast OLED display remains clear and easy to read in both bright and low-light environments, providing real-time visibility of frequency, sound pressure level, operating status, and battery level. This allows users to quickly confirm the output mode and improves overall control and efficiency during field operation.
Automatic Power On and Power Off
The CRY3018 features intelligent automatic power control. When the microphone to be calibrated is inserted into the coupler, the calibrator powers on automatically, reducing button operations and making one-handed field use more convenient. Once calibration is complete, removing the microphone triggers automatic power-off, helping to avoid unnecessary battery consumption. For users who perform frequent pre- and post-test calibration, field work, or high-throughput testing, this design streamlines the workflow and improves overall efficiency and continuity of operation.
