CRY351 Measurement microphone
Free field type; pre-polarization; frequency range: 4 Hz - 40 kHz; sensitivity: 15.8 mV/Pa; dynamic range: 20 - 140 dB
CRY351 is a 1/4'' free-field type pre-polarization measurement microphone. The design of titanium alloy and precision stainless steel makes it not only excellent in corrosion resistance and robustness, but also extremely high stability, so that it is ideal for outdoor and indoor applications. The unique design and smaller size allow it to have the upper limit of up to 40kHz within its frequency range and a very high sensitivity, which makes it suitable for certain special test applications. CRY351 is a kind of high-performance measurement microphone.
