CRY376 Measurement microphone
Free field type; external-polarization; frequency range: 3.15 Hz - 20 kHz; sensitivity: 12.5 mV/Pa; dynamic range: 20 - 160 dB
CRY376 Microphone is a 1/2'' 200 V external-polarization pressure-field measurement microphone that measures the actual sound pressure on the surface of the microphone diaphragm (including changes in the sound field due to the presence of the microphone itself).
Standard-compliant
Compliance with IEC61094-4: 1995 Measurement microphones - Part 4: Specifications for working standard microphones
Compliance with GBT20441.4-2006 Measurement microphones - Part 4: Specifications for working standard microphones
