CRY333 Measurement microphone
Free field type; pre-polarization; frequency range: 3.15 Hz - 20 kHz; sensitivity: 50 mV/Pa; linear range: 15 - 146 dB
CRY333 is a 1/2'' 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. During the test, due to the presence of the microphone, the sound field will be affected and the high-frequency sound field at its position will be changed. Based on this characteristic, the HF frequency response of the measurement microphone is adjusted to compensate for the error caused by the high-frequency sound pressure in the sound field. CRY333 is a kind of high-performance measurement microphone.
