【English Version】
The NA-27 Precision Noise Analyzer is a high-performance acoustic measurement device designed for industrial testing, environmental monitoring, and scientific research. Equipped with advanced sensor technology and intelligent algorithms, it accurately captures and analyzes sound waves within the 20Hz to 20kHz frequency range, making it ideal for machinery condition monitoring, urban noise assessment, and building acoustic performance evaluation.

Key features include a wide-bandwidth high-sensitivity microphone with adaptive noise reduction technology, which isolates target sound sources in complex environments to ensure measurement accuracy. The built-in real-time spectrum analysis module supports A/C/Z-weighted sound pressure level measurement, along with 1/1 octave and 1/3 octave analysis for detailed signal characterization. A 3.5-inch color touchscreen displays real-time spectrograms, time-domain waveforms, and statistical parameters, with local data storage and USB export capabilities.

Technologically, the device integrates a low-power processor and long-life lithium battery, providing up to 16 hours of continuous operation. Its lightweight portable design (total weight <600g) ensures mobility for field measurements. The accompanying PC analysis software enables in-depth data processing and generates professional reports compliant with industry requirements. Target applications span automotive manufacturing, power equipment maintenance, environmental agency monitoring, and acoustic laboratory studies.

Manufacturers prioritize product reliability and user experience through modular design for easy maintenance, backed by a three-year hardware warranty. Widely adopted in global industrial and research projects, users commend its intuitive interface and exceptional measurement consistency, particularly for extended dynamic monitoring tasks.
