CRY343 Measurement microphone
Free field type; pre-polarization; frequency response: 4 Hz - 90 kHz; sensitivity: 4 mV/Pa; dynamic range: 30 - 165 dB
CRY343 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 give it the upper limit of up to 90kHz within the frequency range and a very wide dynamic range. CRY343 is a kind of high-performance measurement microphone.
