CRY3018 Sound Calibrator
The CRY3018 is a portable, high-precision acoustic calibrator compliant with IEC 60942:2017 Class 1. It supports dual frequencies of 250 Hz and 1000 Hz, as well as dual sound pressure levels of 94 dB and 114 dB, with the option to switch to higher SPLs to overcome ambient interference. It features an internal acoustic feedback compensation loop and integrates temperature, humidity, and barometric sensors for adaptive environmental compensation, ensuring linear response and consistent microphone measurements. Additional features include USB-C fast charging, a carbon-fiber housing, and a high-brightness OLED display—making it ideal for on-site calibration of sound level meters, measurement microphones, and acoustic systems.
Dual-Frequency Calibration
Dual Sound Pressure Level Calibration
IEC 60942:2017 Class 1
SPL Feedback System
The calibrator is built around a sound pressure feedback system and integrates high-precision temperature, humidity, and barometric pressure sensors for real-time environmental monitoring. By combining intelligent algorithms with the feedback loop, the unit maintains a stable output signal even when temperature, humidity, or atmospheric pressure fluctuate. This design effectively suppresses environment-induced systematic errors and significantly enhances measurement accuracy and reliability.
Intelligent Power Management
The product supports USB-C fast charging and allows pass-through operation (use while charging). A 5-minute quick charge provides about 1 hour of runtime, and a full charge supports nearly one thousand calibrations. Built-in protection circuitry provides over-charge, over-discharge, and short-circuit protection. The unit also features low-battery warning and automatic power on/off. Together, these functions significantly enhance on-site reliability and operational endurance.
Dynamic Display
The product features a lightweight, high-strength composite housing that offers an ergonomic and comfortable grip while being resistant to both impact and scratches. A high-brightness OLED display ensures clear readability even under strong ambient lighting, and an integrated gyroscope enables automatic screen rotation. A top-mounted status LED provides quick visual indication of device condition in laboratory or field settings, significantly enhancing ease of use.
