CRY346 Measurement microphone
Pressure field type; external-polarization; frequency range: 4 Hz - 70 kHz; sensitivity: 1.6mV/Pa; dynamic range: 30 - 170 dB
CRY346 is a 1/4'' free-field external-polarization 200 V 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 and smaller size allow it to have the upper limit of up to 70kHz within its frequency range and a very high sensitivity, which makes it suitable for certain special test applications. CRY346 is a kind of high-performance measurement microphone.
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
