Ready for working in less-than-perfect environments, the model 130A24 12-mm microphone and preamplifier system excels in applications where moisture, oil splash, and contamination are a concern. Typical applications include brake and tire noise, industrial machinery noise, environmental noise, leak detection and general purpose acoustic tests. The phase characteristics of this microphone are tailored for noise source location applications such as holography, beamforming, acoustic cameras and sound pressure mapping. It includes a replaceable water and dust resistant cover and a rugged stainless steel grid cap similar to those found on high end condenser microphones. Specs include a dynamic range from 30 dBA (inherent noise level) to 150 dB. For additional information, visit http://www.pcb.com/acoustics
