CRY311 Measurement microphone
Free field type; frequency range: 4 Hz - 8 kHz; sensitivity: 100 mV/Pa; dynamic range: 10-146 dB
CRY311 is a 1'' free-field 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 allows it to have the upper limit of 8 kHz within its frequency range and a very high sensitivity, which makes it suitable for certain special test applications. CRY311 is a kind of high-performance measurement microphone.
Standard-compliant
Compliance with IEC61094-4: 1995 Measurement microphones - Part 4: Specifications for working standard microphones
