Product Description
The AWA14408 measuring microphone is a sound pressure field measuring microphone that requires an external 28V
polarization voltage and is mainly used in sound calibrators. The AWA14408 diaphragm is laser-welded, providing excellent stability and environmental adaptability. Its dimensions conform to the IEC 61094 WS2P standard. Assembly and debugging of the AWA144XX series measuring microphones are performed in a cleanroom, featuring low background noise, high stability, and a wide frequency response range. It can be used with multi-channel analyzers, noise analyzers, electroacoustic testers, and other instruments for noise measurement and analysis, and can also replace measuring microphones from other domestic and international brands.
