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.
