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).
