CRY351 Measurement Microphone CRY351 measurement microphone is a pre-polarized 1/4-inch free-field condenser microphone. It is a kind of sensors that converts acoustic signals into electrical signals. The microphones are made of high-quality materials and Titanium membrane, this will ensure its perfect corrosion resistance and keep robustness from other kinds of environmental interference. Laser welding process provides a life-long stability in different temperature and humidity. Its sensitivity is 15.8mV(-36dB) ±2dB @250Hz and the frequency response is 4Hz – 40kHz ±2dB.  Meet IEC 61094-4:1995 Measurement microphones-Part 4: Specifications for working standard microphones  Meet GBT 20441.4-2006 Measurement microphones-Part 4: Specifications for working standard microphones Technique Specification Specification CRY351 Measurement Microphone Field Type Frequency Response(dB) Dynamic Range Limit (ref. 20uPa) CRY Sound Co., Ltd Sensitivity mV/Pa (dBV/Pa) Add: No.31-1, Xianxing Road, Xianlin Industrial Park, Yuhang District, Hangzhou, Zhejiang
