Product Description
The AWA14435 measuring microphone is a 1/4-inch measuring microphone specifically designed for high-precision, high-sound-pressure free-field measurements. It features a wide dynamic range, good stability, and environmental adaptability, meeting the Class 2 engineering measuring microphone requirements. It can be used with the AWA8750 adapter and a 1/2-inch preamplifier, or directly with the AWA14614E 1/4-inch preamplifier. Furthermore, after phase filtering, it can be configured as a sound intensity probe for sound intensity measurement. The 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.
