AWA14522 1/2" Outdoor Pressure-Field Measuring Microphone
Remote Calibration Capability — The dedicated electrostatic calibration protective cap allows sensitivity to be verified remotely, without physical access to the microphone — a major advantage for permanently installed or hard-to-reach outdoor monitoring stations.
Engineered for Outdoor Durability — Purpose-designed for continuous outdoor operation, withstanding extreme temperatures (-30°C to +80°C) and full humidity range (0–100% RH) without compromising accuracy.
Class 1 Precision, IEC 61672 Compliant — Meets rigorous Class 1 engineering measurement standards, ensuring lab-grade accuracy suitable for regulatory and compliance-driven environmental noise monitoring.
Low Noise Floor, High Sensitivity — With a noise floor of ≤18 dB(A) and sensitivity of 47.3 mV/Pa, the microphone captures subtle environmental sound changes with excellent clarity and precision.
Laser-Welded Diaphragm for Long-Term Reliability — Superior build quality ensures stable, consistent performance over extended outdoor deployment periods.
Seamless System Integration — Standard 11.7 mm-60 UNS preamplifier threading ensures easy compatibility with multi-channel analyzers, noise analyzers, and electroacoustic testers.
