CRY332 Measurement microphone
Pressure field type; pre-polarization; frequency response: 3.15 Hz - 10 kHz; sensitivity: 31.6 mV/Pa; dynamic range: 16 - 140 dB
CRY332 is a 1/2'' pressure-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. CRY332 Measurement Microphone is usually used with an ear stimulator coupled cavity, such as CRY318 Ear Stimulator according to IEC60318-1, CRY711 Ear Stimulator according to IEC60318-4 (formerly called "IEC711"). It can also be used to measure the sound pressure in the closed cavity and on the surface of an object. Besides, it can be used as a diffusion field microphone.
