Product Description
The AWA14434 measuring microphone is specifically designed for high sound pressure level (SPL) measurements, with a measurement limit exceeding 175 dB. It features excellent stability and environmental adaptability, meeting the Class 1 engineering measuring microphone requirements of SJ/T 10724. It can be used with the AWA8750 adapter and a 1/2-inch preamplifier, or directly with the AWA14614E 1/4-inch preamplifier. 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.
