CRY371 Measurement microphone
Free field type; pre-polarization; frequency response: 3.15 Hz - 40 kHz; sensitivity: 12.5 mV/Pa; dynamic range: 20 - 160 dB
CRY371 is a 1/2'' free-field type pre-polarization broadband measurement microphone. Thanks to the use of titanium alloys and precision stainless steel, as well as its compact construction and low-sensitivity design, it is not only excellent in corrosion resistance and robustness, but also extremely high stability and a very wide dynamic range, so that it is ideal for outdoor and indoor applications. CRY371 is a kind of high-performance measurement microphone.
